Load lifters are adjustable straps running from the top of each shoulder strap to the top part of the pack body (and ideally to the top of the frame) on many packs designed for overnight carry and beyond. By tightening these straps, the top of the pack is prevented from sagging backwards and a more efficient weight transfer to the hipbelt is achieved by removing weight from the shoulders. An angle of about 45 degrees (running upwards from the shoulder strap to the pack body attachment point) is a good starting point and can be indicative of proper pack torso sizing. Some hikers may prefer to adjust their load lifters depending on terrain, loosening for balance on downhills, and tightening for uphill trail sections.

Load lifters on a backpacking pack help bring the load closer to your center of gravity and place more weight on your hipbelt (hybrid Dyneema ULA Circuit backpack shown).

Using Load Lifters

It is generally best to refer to your pack manufacturer's directions in regards to putting your pack on and in regards to which straps and such to tighten in what order, but load lifters are generally one of the last things you tighten down and adjust when you hit the trail. If you're like me however, you may just adopt a lazy technique and keep them tight just about all the time. Load lifters are what I consider a critical design feature of backpacking packs, and I wouldn't personally consider a backpack without them. For day hiking with lighter loads however, they are not as critical. For a list of backpacking packs on the market, many of which feature load lifters, you can see this page at REI Co-op.

Load Lifters are not to be confused with Load Hauler, a term often assigned to larger, more robust backpacks designed for carrying heavier loads. For more on packs, see our guide on how to choose the best hiking and backpacking backpack.
