Often referred to simply as "sil". Nylon fabric impregnated with a silicone coating on each side. Fairly economical. Typically offered in a 30 denier (30D) fabric weight, with lighter options sometimes available. Often used in lightweight shelters, tarps, and backpacks due to its strength, light weight, and waterproofness. Non-breathable.

Silnylon has been a popular backpacking fabric for many years, and although silpoly (sil-polyester) has gained traction in recent years, silnylon's popularity has been for good reason.
Silnylon Performance in a Backpacking Scenario
While very strong, silnylon fabric can sometimes suffer slight leakage under heavy water pressure such as that from a heavy thunderstorm (misting) or from kneeling against the fabric as water lies underneath. This can be seen when used in a groundsheet application for example, which could exert a high level of pressure against a very small portion of the fabric if kneeling on soaked ground (high PSI exceeding the hydrostatic head). Look for silnylon with a higher hydrostatic head rating to help in this regard.
Silnylon can “sag” when wet, requiring one to re-adjust their tarp or shelter. This has caused a surge of silicone coated polyester (silpoly) to be used in recent years, which stretches less and is more UV resistant, but not as initially strong, abrasion resistant, or as puncture resistant as silnylon (the stretch of nylon can be a benefit for durability).
For backpacking applications silnylon offers a nice blend of strength, abrasion resistance, weight, waterproofness, and value when it comes to budget. For complete waterproofing silnylon seams will need to be seam-sealed with something like Seam Grip SIL as the fabric cannot be factory taped. Some manufacturers use a fabric that is PU (polyurethane) coated on one side to solve this issue of taping (for example the Sea to Summit UltraSil Dry Bags), although the PU coating reduces the strength of the fabric.

An important core backpacking gear item, your backpacking sleeping bag needs to be light enough to carry easily, pack small enough as to not take over your entire pack, and most importantly keep you warm and comfortable at night. In this guide we’ll focus on the best backpacking sleeping bags currently on the market by temperature rating.

As this is a backpacking focused article weight of the sleeping bag and warmth to weight ratio will be of a paramount focus here, with down bags ruling the roost. For a basecamp scenario, synthetic bags would be worth consideration. See our guide on down vs. synthetic insulation for more information and background. For the purposes of this article, we will focus on features, weight, and performance.
Best 30F+ & Summer Rated Backpacking Sleeping Bags
This can be a complicated category with many options. Bags in this range can be very light, but early morning hours can be a bit crisp and ample warmth will be appreciated during the night. My pick hands down would be the Zpacks Classic 30 degree sleeping bag. Weighing in at just 14 ounces and going for $440, this bag is made with DownTek 900 fill power water resistant down and is available in 7 different sizes.
Going to a hoodless sleeping bag (I mostly use the Zpacks 20 degree) has changed my backcountry sleeping for the better – now I can turn with the bag, or inside the bag, no matter. Additionally with the zipper on the bottom maximum heat is retained and you have no zipper at the top (leaking the most hot air) no matter if you’re a back sleeper or a side sleeper. In milder conditions above the shoulders just a warm hat works well for me, but if it gets cold at night you can add in an additional goose hood.

Traditional top-tier manufacturers include Feathered Friends and Western Mountaineering. When it comes to Western Mountaineering, they offer a variety of bags in this category, many that don’t have much difference between each other from a big picture point of view. Their MegaLite 30 degree sleeping bag weighs in at 24 ounces and is a nice option if you like more traditional design features. The MegaLite uses 850 fill down and is a wider bag with a passive draft collar that I’ve found is sufficient down to around freezing.
Western Mountaineering bags aren’t cheap – the MegaLite will set you back about $600 – but with proper care these are bags that will last darn near forever. For slimmer users and in warmer conditions one could consider the Western Mountaineering SummerLite (around $500, 19 ounces) – although we’ve found this one starts to take on a chill as temperatures close in towards the freezing mark, it would be ideal for warmer nights.

Both the MegaLite and SummerLite from Western Mountaineering feature a fully baffled construction (the bag is not sewn through to create the baffles – a sewn through bag results in a lighter and possibly less expensive construction but will have cold spots when temperatures drop).
The Western Mountaineering FlyLite is a newer bag that is an option for warmer weather trips – it’s rated to 36 degrees, weighs just ~14 ounces in a standard width, and retails for just over $500. This makes it the lightest fully baffled bag Western Mountaineering offers.

Draft tubes, draft collars, continuous baffles, and so on are not as critical during warmer conditions and their omission can save weight, but I find I've always appreciated these features in the field.
Feathered Friends additionally offers top of the line down sleeping bags including the Hummingbird UL 30 ($550, about 22 ounces). This is a narrower bag (saves weight, more efficient) so keep that in mind, but if you’ll fit, as with Western Mountaineering this 950 fill power down bag is expensive but worth it.
For women Feathered Friends offers their Egret UL 30 ($550, about 24 ounces) with an even narrower cut but in a more women’s-specific shape. Wider bags from Feathered Friends include the Swift UL 30 ($580, about 26 ounces) and the more middle of the road width wise Swallow UL 30 (24 ounces, $570). It will be hard to go wrong with a Feathered Friends bag, so long as you get the right fit.

Another option is the REI Co-op Magma 30 (averaging around 25 ounces, $380) – offered in no less than 9 sizes for an almost custom type of fit, this bag keeps it lightweight via use of an 850 fill power water resistant down, standard features, and you even get an interior pocket. While of all things backpacking a down sleeping bag is one place where I would not try to cut budget, this is one bag that could be considered more in the budget category if you catch it on sale.

Best 20 Degree Range Sleeping Bags
Everything in nature seems to change below freezing, and at these temperatures I find that it becomes more important to consider those extra features like a nice draft tube and hood, with a draft collar being very much appreciated. For me and many others that backpack mostly in mountain terrain, the 20 degree bag gets the most use 3 seasons out of the year. These are your bread and butter sleeping bags, and from my perspective if you’re looking for the best sleeping bag in this category, you’ll likely be looking at the same brands we’ve previously discussed.
Feathered Friends offers their versatile Hummingbird UL 20 (24 ounces, $610) – with the Feathered Friends Egret 20 (~28 ounces, around $610) being a women’s-specific option in this temperature range. These are narrower bags to save the most weight. However, if you like a little more space in a bag as I do, check out the Swallow UL 20 (27 ounces, $630).

In regards to Western Mountaineering, we can narrow this down to the venerable UltraLite 20 degree (29 ounces, $630) – which is your narrow / standard option – and the wider and perhaps more comfortable 20 degree AlpinLite (31 ounces, $710). Although it’s a bit heavier the AlpinLite’s space wins out for me out of these two bags, but as with Feathered Friends, you can’t go wrong here.
That said as previously mentioned and although I have had many a comfortable backcountry night in a WM AlpinLite, my preference for a backpacking sleeping bag has evolved towards the hoodless category. The Zpacks 20 Degree Classic sleeping bag (~19 ounces, $460) is my current choice for a bag in this temperature range – I find at these temperatures a hoodless bag is ideal (so long as I wear the warm hat I already take and wear a jacket with a hood). You can find my review of the Zpacks 20 here, although Zpacks has since updated the bag just a bit with upgrades. Zpacks again also offers their goose hood, but with a warm hat and jacket hood, I haven’t personally needed this until temps fall below 20. That said if you’re not ready to give up your sleeping bag hood, Zpacks also offers their 20 degree Mummy sleeping bag (23 ounces in medium standard, $580) with a built-in traditional hood.

When on sale, for a more budget option in this category we’ll go ahead and put the REI Co-op Magma 15 in this category (comfort limit: 21 degrees). With a weight of around 36 ounces depending on size and retailing at $429 full price, this bag offers a very reasonable weight in 9 different sizes for a tailored fit, and at a very reasonable price especially if you catch it on sale.

Best Winter and Cold Weather (Zero and 10 Degree) Sleeping Bags
I find that it’s more versatile to have 2 warmer rated bags, combining them to form a winter sleep system when needed for cold winter trips rather than keeping a bag from this category on hand. As an example, I’ve combined a 20 degree and a more summer-oriented bag and stayed warm (with appropriate sleeping pads and a total r-value for the temperature) on winter trips nearing minus 20F. That said if you have one 3 season bag that covers all seasons other than winter, sleep especially cold and want a warmer bag for 3 season mountain trips, or are looking to add in a dedicated winter bag, a bag in this category may be desired.
Same players, different temperature ratings again here. The 2lb., $735 Western Mountaineering VersaLite 10 degree sleeping bag is a solid choice on the warmer end of this category. One nice thing about the Versalite is that it’s in the middle width-wise – just right. Going back a bit to their 20 degree options if the UltraLite was a bit too tight, and the AlpinLite a bit too wide, the VersaLite will likely be a perfect choice.

For a women’s-specific bag check out the 10 degree Feathered Friends Petrel UL 10 (2lbs, $660). This is a super high quality women’s bag that is not unheard of on packing lists even for summer trips in the mountains for cold sleepers. As a women’s bag I haven’t personally used the Petrel, but having seen this bag being used in the field on many occasions I’m never surprised by the loft of Petrel – you may need a bigger pack!
At these temperatures I do think a sleeping bag hood is something good to have – you want to retain every bit of heat your body puts off during the night within a singular compartment and bag. Thus the 28 ounce, $600 Zpacks Mummy Sleeping Bag in a 10 degree would be well worth consideration here for hikers looking to save weight.

On cold winter trips, I prioritize warmth and features over weight.
The colder it becomes the less I am personally concerned about weight – I prioritize warmth and comfort – and the last thing I’d want is a constricting bag on a winter night that could last 16 hours or more. In their wide mummy series the Feathered Friends Raven 10 UL (34 ounces, $700) would make for a top of the line choice in a 10 degree bag, but if saving the weight is more critical (via less width), the Feathered Friends Lark 10 UL (31 ounces, $680) would be the next logical choice here.
Pushing the rating to 0F Feathered Friends offers their women’s Murre ES 0 degree bag (3lbs, $780) as well as their Ibis ES 0 Degree (50 ounces, $820). With a focus on heating efficiency, both of these bags have a bit of a narrow cut to be aware of – as with many things, there are pros and cons.

Deep Winter / Expedition Sleeping Bags
While I prefer to combine 2 bags to make a poor man’s expedition bag for general winter backpacking trips in the lower 48, if I were to plan an Arctic expedition, a cold mountaineering summit attempt, or for some type of cold northern basecamp type scenario, an expedition bag would certainly be appreciated in these unique circumstances.

Feathered Friends and Western Mountaineering offer some very intriguing, and impressive, choices here that both throw plenty of goose down at the issue. The Western Mountaineering Bison Stormshield (69 ounces, $1360) is rated to -40F with 10” of loft and a weather-resistant shell. This bag is sized generously for additional comfort on those long winter nights.
On the Feathered Friends side, their -40F solution can be found in the Snow Goose ES -40 (65 ounces, $1170). This bag is another bag that’s sized generously for more comfort and space if you’ll be spending a lot of time in your sleeping bag. If -40F isn’t warm enough however, the 78 ounce, $1360 Snowy Owl ES -60 bag from Feathered Friends may be up your alley for the most epic of arctic level expeditions.

Whether it's an expedition sleeping bag rated to 60 below or a featherweight summer bag that packs up smaller than a water bottle, there is a sleeping bag on the market for every possible use and scenario.
In Conclusion
A critical item on your gear list, there are a few ways to go about your sleeping bag strategy. You could choose to go with a bag rated for the lowest temperatures you’ll ever backpack in, but this bag may be overly bulky and heavy for warm summer trips (albeit workable). To save weight, I like to go with a 2 bag system, a warmer bag for downright summer-like weather, and a 20 degree bag that gets the vast majority of use for 3-season trips in the mountains where lows in the 20s are not uncommon in August. When I head out on a winter trip, I combine them.
Whether you opt for a 1 bag approach or a multitude of bags ideal for every scenario, sleeping warm adds to any trip – and while a slightly heavier and warmer bag may not rule the ultralight spreadsheet, some temperature rating buffer is always appreciated at night when you’re out there.
For a list of sleeping bags from various manufacturers that you can sort and filter by temperature rating and more, see this page at REI Co-op. For background info on sleeping bags, refer to our guide on How to Choose the Best Backpacking Sleeping Bag.

One of the big 3 of backpacking gear choices (backpack, tent or shelter, and sleeping bag), the backpacking backpack you choose will have a profound impact on your comfort during the hiking day. Your pack will also be one of the more expensive items you’ll purchase, and to get the best pack within your budget a little research will be needed as there are a myriad of packs out there on the market.

In this guide, we’ll look at the best backpacking packs currently on the market based upon anticipated pack weight and packing category (ultralight, lightweight, heavy weight) along with some budget options as well. For the purposes of this guide, we’ll focus on performance, availability, reasonable price, and reasonable longevity for the intended purpose.
Best Ultralight Backpacking Backpacks
If you’re a weekend or overnight backpacker and / or manage to keep your total pack weight at around 25lbs or less, more ultralight backpacking packs may be worth a look. That said, if you do plan on going over this weight from time to time, and prefer a quiver of one, the next section in this article may be more appropriate to evaluate. For ultralight loads however, the frameless ULA Photon (35L total, 26 ounces, $220) from Ultralight Adventure Equipment is not the lightest pack out there, but is tough and has excellent comfort at these weights along with a livable pocket configuration. For a bit of a space and a carrying ability upgrade, look at the ULA Ohm (63L, 34 ounces, $280) as well as the ULA CDT (54L total, 27 ounces, $220).

The Zpacks Nero Ultra 38L (38L total space, 10 ounces, $250) offers an ultralight option for the lightest of ultralight packers, but in typical Zpacks style still has organization and features you need in a pack of this nature. The Super Nero Ultra 50L boosts the space up to 50L total, with a pack weight of just 12 ounces at $270. Both of these packs are suggested for 20lbs or less of total pack weight. Another option is the MLD (Mountain Laurel Designs) Burn. This pack weighs in just over a pound and retails for $325 with 38L of storage. Featuring the tried and true combination of roll top main compartment, outside pocket, side pockets, and hipbelt pockets, the Burn is a nice option for ultralight overnights or beyond, so long as you are indeed focusing on the “ultra” of ultralight.

Best Lightweight & Long Distance Backpacks
This is the bread and butter category of backpacking packs if you’re focused on lightweight backpacking, planning longer trips where saving weight is a priority, or if you're planning on thru-hiking a long trail. These are the packs that are just right most of the time, just fine (if a little under-loaded) for an overnight, and can be pushed for longer trips – although they may not be the most comfortable for hauling heavy loads the first few days out and until some of that consumable weight is reduced.

In this category and if your pack weight will be under 35-40lbs two packs from ULA Equipment have been a favorite choice of both mine and the backpacking community for years. My pick is the ULA Circuit (total volume 68L, 38.5 ounces, $300) that I’ve used on overnights up to 10 day trips and everything in between, although it’s definitely pushing it for trips over a week for me (whether you’d want to grab a pack from the next section in this article is a personal call).
If you’ll be packing a little heavier, trend towards longer trips, and / or like more space the ULA Catalyst (75L total, 44.4 ounces, $320) will make more sense. To save a little weight and for a more waterproof pack Ultra versions of both of these packs are available. These two packs feature my favorite storage configuration for the trail (as previously described): large roll top main compartment, large outside back pocket, side pockets, and hipbelt pockets. In either case, you simply cannot go wrong with these two venerable ULA packs if you’ll be carrying less than 40lbs fully loaded (I’ve had 50lbs in the Circuit, not suggested but the pack was no worse for wear). And as a quick note if you're looking for a great kid's pack look no further than the ULA Spark.

Another and newer pack to check out in this category is the Durston Kakwa 55 (around 60L total, about 31 ounces, $200-$260). This pack can be either had in the more affordable UltraGrid fabric option or Ultra 200X. Either way you get a pack with impressive organization at reasonable prices, and a pack that’s quite light but still can carry up to 45lbs.
A note on Ultra: while many manufacturers have begun using Ultra (100X / 200X / 400X) fabrics for packs, durability has been mixed on the original fabric and the jury is still out on newer, further reinforced X versions. That said an Ultra pack will get you a completely waterproof pack (except seams unless taped).
UltraGrid however, is a heavier denier nylon with a UHMWPE gridstop and a PU coating on the inside. This coating is rated at a 1500mm hydrostatic head – that’s as waterproof as some tents on the market. Fabrics similar to UltraGrid have proven themselves over the years. They will become more water-resistant in time, but these fabrics have held up very well to the trail – on or off trail for that matter – and have handled abrasion situations very well in my experience. Long story short, it is hard to beat a good gridstop fabric for packs.

Gridstop may not be the most waterproof, but I have gridstop packs with a decade+ of usage that are still quite water resistant and there are other ways to keep your backpacking gear dry. This would include using a pack liner or a large dry bag or two…or alternatively a trash compactor bag would be suggested in regards to pack waterproofing. Gridstops aren’t as trendy as laminates, but I fully expect 10 years or more of use out of packs made with these gridstop ~200+ denier nylon fabrics and there is a lot to be said for that.
Back to backpacks, for the lightest of the light, the Zpacks Arc Haul Ultra 60L (60L total storage, about 22 ounces, $400) is worth consideration – this pack is rated to carry 40lbs via a carbon fiber frame system with integrated back ventilation and as a bonus is also available in a women's specific version. The pack uses a lighter Ultra 100X to save weight – so this pack will be better for users that are willing to be a little careful with their gear in order to save the weight.

Best Load Hauler Backpacking Packs
Weight (of the pack itself...or weight carried within it for that matter) can quickly spiral out of control in this category, with some manufacturers offering packs here that can weigh well over 5lbs. In this category we have a few main venerable larger players, with one example being the Gregory Baltoro and the Gregory Deva series, in particular the Baltoro 75 liter (~80 ounces, $360) and the Baltoro 85 Pro (around 88 ounces, $400), with the women’s version being offered in the Deva 70 backpack (about 75 ounces, $360) as well as the larger Deva 80 Pro pack (~84 ounces, $400).
If you’re looking for a cushy mainstream get-it-done pack to haul large loads that can be on your doorstep a few days from now, the Baltoro and Deva packs have been a go-to for many years and are rated to carry up to 70lbs. Saving weight for the pack itself is not however a strong point here.

If you’ll be hauling a heavy load (long trips, lots of food and water, or extras like packrafts or camera gear) but still have a lightweight approach like me, you may need to look at smaller companies to fill this niche. Leaders in this category include the Superior Wilderness Designs Wolverine 95L (a 70L is also offered) pack as well as their 95L Big Wild pack (no large outside back pocket), also offered in a 70L version.
While color is usually not my primary concern when selecting a pack, these two SWD packs for better or worse are only made in Ultra 400X fabric which only comes in white or black – which I’d have to say, would be towards my last 2 choices when it comes to something like a pack or tent color. That said, these packs are rated to carry up over 50lbs for around $400 and will come in around 40 ounces for the pack itself, plus or minus depending on options. Be sure to check out their available add-ons if you want something like a hydration port or hipbelt pockets.
A couple other packs stand out here: Nunatak makes extraordinary gear and offers their Plateau Pack (around 40 ounces, $350) with an up to 75L capacity and capable of carrying 50+ lbs. If you need something even larger, check out the Sockdolager Equipment Bad Larry pack ($475, 3lbs or so depending on options) with Dan Ransom’s tubular aluminum twin stays. The 90L Bad Larry was designed for packrafting, but packrafting specific features can be removed and you end up with a competitive backpacking load hauler pack. These two packs are more custom built and you’ll have to see if things like hydration ports or hipbelt pockets can be added. Be it Superior Wilderness Designs or Nunatak or Sockdolager, plan in advance and buckle up for some wait times.

Seek Outside also offers a couple packs worth checking out – although Seek Outside seems to lean towards the lightweight backcountry hunting crowd, some of their products can be adapted to lightweight backpacking like the 79L Divide 2.0 ($505, 55 ounces). However, Seek Outside takes no custom requests so if you want something like a hydration port, you’re out of luck unless you want to start cutting and sewing yourself. That said Seek Outside’s frames are uniquely rated for pretty much whatever weight you can physically carry, so if you’re wanting to sign up for a suffer fest in regards to pack weight, these are the packs that would be up to the task.

Best Budget Backpacking Packs
If you want to keep it under $200 (at least before shipping and tax) – which I would very much consider a budget range for a backpacking pack – the previously mentioned Durston Kakwa 55 in UltraGrid offers quite a bit of value in this category as long as you’re packing somewhat lightweight, with the REI Co-op Flash 55 (about 55 liters, just under 3lbs, $200) offering another option that’s worth ample consideration. The REI Co-op Flash has the bonus of being offered in both a men’s and women’s version and in my experience, this line has demonstrated good value and very acceptable performance. Another interesting sub-$200 option can be found in the Osprey Rook 65 backpack (men's) and the Osprey Renn 65L (women's). Designed to carry up to 40lbs, these packs offer 65 liters of space, basic features, and can be had for about $190 while weighing in just under 4lbs.

A pack from the REI Co-op Flash series.
It is also worth checking out the REI Co-op Outlet from time to time, as you can often find many packs or last year’s model that will be perfectly serviceable at a discount here. For a budget load hauler pack, this can be tough since these are typically the larger and more feature-packed (expensive) options. The aforementioned REI Co-op Outlet is a good place to start your search. That said the Kelty Asher 85 is also worth consideration – as you’d expect it’s an 85 liter pack that weighs in close to 6 pounds, but can carry a heavy load and retails for just under $200 full price.

My Approach to Backpacking Packs and in Conclusion
If you like to keep your gear simple and want one pack to do it all, there are a few ways to go about your approach. You can pick a pack rated for the heaviest load you’ll ever carry, and while it may be a bit much for shorter trips it will work. Or you could go for a pack rated for the typical load you’ll carry, but your shoulders may be complaining at the start of longer trips. This can be done if you’re only rarely expecting to take these kinds of trips and saving the cash is more important than comfort (not my choice).

You could also pick a pack for overnights, another for most trips in the middle, and an even larger pack for load hauling and the longest excursions. For me, I like two packs: one do it all (from the lightweight and long distance category) and another load hauler for extended trips with extra gear. One advantage of this route (multiple packs) is that it spreads the wear out a bit and your packs will last longer.

A backpacking sleeping pad very importantly provides warmth by insulating us from the cold ground at night, and ideally a sleeping pad will also provide sufficient comfort to allow for a good night of rest. As an item that’s one of the heaviest and bulkiest core gear items you will carry on any backpacking trip, the sleeping pad requires some thought and consideration when it comes to selection and application.
With a multitude of options available there's a sleeping pad to specifically suit any season and backpacking trip, as well as those that offer a wide range of versatility across many situations. In this article we'll look at things to consider and features of some of the best sleeping pads on the market today.

When considering a backpacking sleeping pad, weight, warmth, comfort, and durability should all be considered.
R-Value and Warmth
The most important function a sleeping pad serves is to keep you warm; although we all like to be comfortable we can’t be comfortable if we’re cold. Thus, consider a sleeping pad’s r-value when making a choice. However, there’s no free lunch; the warmer the pad the heavier and bulkier it will be. As such we have to seek a balance just like anything else. For general 3 season use here in the Rockies where it always gets a bit chilly at night, I target a sleeping pad with an r-value of at least 3. Combined with an appropriate sleeping bag for the forecasted lows of course, I’ve found this to provide sufficient warmth into the higher 20’s.
When it will be colder, I combine this pad with the thinnest (1/4" or less) and lightest generic closed cell foam pad I can find particularly of the Evazote foam variety that can easily be cut down to a custom size or folded over to double up if needed. Options like the ULA Siesta pad or this option on Amazon, and foam pads sometimes carried by many cottage makers / vendors also work well. Essentially, you are looking for a thin 1/8" to 1/4" foam pad that will cover you width wise (depends on your main pad width of choice), and at least offer torso length coverage or more. This system will keep me comfortably warm to the high teens.
If it will be colder than that I will combine my usual sleeping pad with a thick foam pad of nearly an equal r-value. As an example, the Exped Synmat UL7 – find our full review here – which is my choice for an inflatable pad – combined with something like the Z Lite Sol foam pad and the aforementioned thin foam pad will provide a total r-value approaching 6. A combo like this has kept me warm on winter trips well below 0.

On this trip with a low for the night well below 0, I packed both this Ridge Rest Solar plus an insulated inflatable.
Some inflatable pads like the Exped Ultra 1R feature no insulation at all (r-value around 1) and basically provide mostly comfort from the ground, but not cold ground. These pads are lighter and cheaper, and might be useful for a dedicated summer sleeping pad in warm locales. On the flipside some winter sleeping pads, such as the Exped Dura 8R or the NeoAir X-Therm NXT MAX, are heavily insulated and would be sufficiently warm all on their own for cold winter camping and for cold sleepers.
On both sides of the coin though each are on the specialized end of the spectrum; I prefer the adaptable approach of using one 3-season rated pad, and then adding in a thin, or thicker foam pad when needed for colder temperatures. For the 3 season pad I like an inflatable to provide the comfort and some baseline level of insulation, and when combined with the additional foam pad the foam pad protects the inflatable and will even serve as a fail-safe should the inflatable spring a leak.

As a general starting guide an r-value of 2+ has been useful for me on summer trips in the mountains and for 3 season use in warmer locations; warm into the 30 degree range. I find an r-value of 3+ most useful all-around, providing sufficient warmth for most 3-season trips in the mountains and down to the 20 degree range. However if you're a cold sleeper or sleep warm, you can implement some respective addition or subtraction here. For winter trips I do not mess around and take a combination of pads totaling a 5-6+ r-value. Pads that feature an r-value under 2 I find useful only as part of a larger system (as a solution to boost warmth as part of an overall sleep system), but not on their own.
Sleeping Pad Size
Sleeping pads are usually offered in multiple lengths and depending on your height and use, an appropriate fit can be found. If you’re going with an ultralight approach a shorter pad can work that offers coverage for the most important part of your body – your torso and core, but your feet and legs will hang off the end. To insulate this area you can pile gear and your backpack – that might just have an insulating foam backpanel – at the bottom of the shorter sleeping pad. This will save the most weight, but still will not be as warm or as comfortable as a longer pad. My preference is to use a pad that’s at least close to my height. A few inches shorter is fine as we often sleep a bit shorter than our height with knees and back bent, etc., or longer than your height offers the most luxury. Either way, by getting your whole body on the pad you will sleep warmer.
The standard width for most sleeping pads is 20 inches. Often a wide version (not really standardized, but usually 25”) is also offered and even up to double wide pads for two like the Exped Ultra 3R Duo sleeping pad are offered. Two one-person pads can always be strapped together – Sea to Summit makes the best solution for this I’ve used. Preference will of course depend on your size and sleeping style. A 20” pad works for me, but there’s not much wiggle room and I do sleep better on a wider pad that offers more room to bend your knees for side sleepers or for toss and turners. Many tents are based around this 20” width standard, so be sure your pad will fit in your shelter of choice and combined with whatever width pad your partner may have if you’re sharing a tent.
Either way longer and wider pads offer more comfort but at the cost of an increase in weight and bulk. I’ve accumulated several sizes over the years, so on trips where I’ll be covering a lot of miles I take a standard 6’ pad; on more relaxed trips I like the comfort my Synmat LW (Long/Wide) offers. No matter the size, you will find sleeping pads available in both a traditional rectangular shape as well as in tapering, mummy shapes that narrow towards the feet. While tapered pads offer some weight savings, a rectangular sleeping pad offers more room.

Weight
A great target for an adequately warm and comfortable full length standard 3-season sleeping pad for most locations is around 1lb with the weight falling below that as we get into shorter and/or less warm pads, and above that as we get into longer, wider, and warmer pads. Save for a dedicated winter pad, approaching the 2lb mark is best reserved for sleeping pads in more of the super comfortable and warm, but heavy and bulky car camping variety. If you'll be focusing on car camping, weight shouldn't be a concern. The best car camping sleeping pads will be those that are warm, comfortable, and durable. That said, back to the trail...
Closed Cell Foam Pads
The simplest and cheapest option to go with is a closed cell foam sleeping pad. I’m much more comfortable on an inflatable pad, but as previously described, I still have an assortment of closed cell foam pads in my gear stash to combine with an inflatable pad for additional warmth on shoulder season and winter trips with my 3 season rated Exped Synmat UL7. However, the foam pad excels in the reliability department – it won’t leak and you don’t have to carry a patch kit. They are also usually cheaper.

The downside is they pack bulky and you will probably have to carry it on the outside of your backpack. This can be a pro though, as the pad will be easily accessible to use as a sit pad on breaks and for lunch. Foam pads are usually just around an inch thick or a bit less, and then compress further when you’re on it. You will definitely feel the ground and any rocks or roots that might occupy your campsite, but if the comfort works for you the foam pad is a reliable and affordable choice. Note that you will want to avoid open cell foam pads, as they will absorb water and when they do they take a long time to dry. Reserve these for use on the futon at home.

Foam pads are bulky to carry, but convenient for breaks.
Most foam pads can be had for under $50. Some popular options include such venerable choices as the generic blue foam pad, the Therm-a-Rest Ridge Rest (a classic), and the more conveniently packed Z Lite pad. And in recent years, you can now find that classic foam pads from Therm-a-Rest have been updated with an aluminized reflective (warmer) coating as seen in the Z Lite Sol pad for a small boost in warmth and durability. Overall a foam sleeping pad will above all be dependable, but not the most comfortable or easy to carry.
Inflatable Pads
Inflatable sleeping pads offer a few advantages and disadvantages compared to their closed cell foam cousins. Usually thicker than foam pads when inflated, an air pad can keep you totally off the ground and the inflation level can be adjusted to suit your own comfort preference. Thinner inflatables are better for back sleepers and the thicker variety better for side sleepers.
If you toss and turn, look for a design that is raised around the sides a bit to help center you on the pad and keep you from falling off in the night. Inflatable pads also pack smaller, usually around the size of a Nalgene and even a long / wide inflatable will easily fit inside a backpack. Most air pads usually feature baffles arranged in a horizontal, vertical, or sometimes in a pod like arrangement like the Sea to Summit Ultralight – one of our tested sleeping pads we’ve previously reviewed. Preference varies; I like the lengthwise tubes that I find help me stay centered on the pad. Self-inflating pads usually have a flatter sleeping surface.

The downside of inflatable pads is that they can be punctured, baffles can fail, you have to inflate it, and to be sufficiently warm inflatable pads will use insulation or special baffles that bump up the price. When I carry an inflatable, I also bring a patch kit along just in case, and use care where I put the pad. For inflation I prefer to not use my breath, not only can this be a little difficult at high altitudes after a long day, but it introduces moisture. Many manufacturers offer a pump bag solution – like the Exped Scnhozzel I use, and battery operated pumps are even available.

The standard of inflatables a couple decades ago, some are still self-inflating, but the self-inflating pad has become rarer in recent times. Keeping air pads protected and inside your tent is ideal. Many people may also take a smaller foam pad to use as a dedicated sit pad in this situation. The texture of sleeping pad surfaces vary, and some inflatable pads can be a bit noisy and some can also have slick surfaces that can migrate around the tent, or have you migrating on top of them at night. Some strategic dots of Seam Grip SIL on your (especially if it’s silnylon) tent floor can help mitigate the slipping, and if you combine an inflatable with a foam pad of any type as I often do in colder weather it will mitigate this issue.
For an inflatable lightweight insulated sleeping pad, you are probably looking at something in the $100-$200 range. Popular inflatable pads can be found in the Therm-a-Rest NeoAir series (view at REI) that utilize a combination of baffling and aluminized reflective features to provide warmth, options from Sea to Summit that use microfiber insulation, and many options of various insulation types exist from makers like Big Agnes and Nemo Equipment. The best backpacking sleeping pads will feature a blend of warmth, weight, packed size, and durability. If you choose the most extreme of any category, it will likely be at the cost of something else.
My System
Just like sleeping bags, selecting a backpacking sleeping pad is without a doubt, a huge balance between weight, comfort, price, reliability, and warmth – and while there’s no best sleeping pad and no free lunch, with so many options out there there’s no doubt the right sleeping pad that suits your style can be found. As a side sleeper who values all the above points fairly equally and has been testing sleeping pads for decades, I like a comfortable 3 season inflatable pad as the main cog in my sleeping pad system, and add in a thin foam pad for just a touch of additional warmth when it's needed and a thicker foam pad for winter conditions.

Fall – a time of the year when the crisp air is enjoyed and the greens of summer are replaced with hues of orange and yellow. And, it’s also the time that we as hikers contend with hunting season. Strategies for hiking during this time range from doing nothing different at all to simply staying home, and while hunting season is a worthy pre-hike consideration, by taking a few steps and modifying our gear and routine just a bit, we can continue hiking during hunting season with a few changes to our approach. Here are some considerations plus some strategies that I’ve found helpful for hunting season hiking.

A hat is one way to add a blaze orange clothing option, and wearing a headlamp during times of dawn and dusk is another good practice during hunting season.
Add Blaze Orange Into the Clothing and Accessory Ensemble
During the fall hunting season I like to add in some bright colors to my clothing arsenal, and very preferably blaze orange. Either way I like to stand out – exactly what I want this time of year, and hunters, who are likely wearing blaze orange themselves, are keyed up and actively looking for this color. While I personally prefer to blend in and wear natural colors at all other times of the year, during the fall hunting season I definitely embrace my extrovert side. Where to get the gear? Amazon will have just about anything you’re looking for in blaze orange (like the blaze orange Carhartt knit cap in the photo above), and local hardware stores might even have a decent selection of cheap, bright, and effective hunting season gear. This also goes for my dog – I look at blaze orange collars, bandannas, or jackets this time of the year. But as always at any time of the year, though especially during hunting season, keeping dogs on a leash or at my side and under voice command is something I always practice. If I'll be out hiking at dusk or dawn, I make sure my headlamp is on.

When planning approaches to hiking during hunting season, don't forget others in the group.
Hike Around Season Dates
Using my state’s fish and game website, I also like to plan trips around the season dates when possible and try to avoid opening and closing weekends / opening and closing day, and holiday weekends in popular areas. Middle of the week in the middle of the season is usually better timing while the season is active. I like to especially remain “bear aware” as the season winds on, as often times successful hunting activities may increase the presence of other animals as well. Hunting season often typically begins with an archery only season, and planning a trip during this time is great when more comfortable hiking at that time compared to the general firearm dates.
Head for Remote, and Preferably Wilderness Areas
Big game animals are heavy, and thus hunting is often closely tied to motorized vehicle use, ATVs, or horses. In wilderness areas I can avoid the motor vehicle aspect, and wilderness hunting horse trips are often led by experienced and local guides. But generally, just like if I'm looking for solitude any time of the year in the backcountry, the farther I go in and the farther from the road and trailhead I get, the less people…and hunters…I typically see. Many national parks also ban hunting, so this might be a great time to explore and get some national park hikes in if able.

Consider Where Hunting Will Be More Concentrated
Based upon wildlife activity, I can often get an idea where most hunting will take place. As an example and here in the Rockies, if we have a hot summer that’s stretching well into fall game animals could still be found in their higher elevation haunts. Early winter? Game may be pushed to lower and warmer elevations and closer to their winter ranges with the hunters following close behind. I like to plan trips around this. The nuances of every locale are a bit different, but you get the idea. Hunters in the area, outdoor stores, and land management agencies (forest service, game and fish, etc.) offer a great way to learn about these nuances and I find I can learn some interesting aspects about the wildlife patterns in the area. I've found it's good to be careful how I ask…it's not likely to get a very straight answer if hunters are asked where the best hunting spots in the area are.
Alertness When Hiking Off-Trail
Not only do I make my presence known by sight (adding blaze orange as described above) but also by sound. I have encountered hunting on trail, but generally there shouldn’t be encounters with any active hunting while on a marked trail (though I may encounter hunters themselves), and I find I will be more likely to cross paths with someone actively on the hunt off of it. Just like in bear country, I like to give a quick human vocalization every now and then, and stop to listen as well for the calls of game at intervals. Is that an elk, or someone trying to call one in? I’ve encountered both while hiking off-trail during hunting season. Either way I find a quick hello, hi there, or phrase of choice is not a bad idea. In combination an outdoor whistle can be considered, which may carry farther in difficult conditions.


Even though wildlife was abundant on this trip, due to the remoteness of the area hunting (and other hikers for that matter) would not be a likely occurrence.
Final Thoughts
On one hunting season backpacking trip no less than 30 seconds after parking at the trailhead and starting off towards the wilderness boundary, I encountered a hunter near the trailhead (see point 3 above), and a few minutes after moving on down the trail, a series of shots were heard. Hunting season is definitely a time when we have to share the trail, but overall and with fall one of the best times to be outside (and winter is coming!), the season can be enjoyed with a few extra considerations before heading out, from destination choice, to season timing, to adding blaze orange options into the clothing mix. And just like dealing with the conditions of any other season – be it throwing in winter gear or mixing up the gear and approach just a bit for the shoulder seasons, it’s all about preparation and approach and just getting out there.
