Help with drybag

[Coreywinter]

Going on a canoe/camping trip with a few fairly long portages. I want to use my cabelas drybag for all my gear but it only has one shoulder strap. Does anyone know the best way to put a more comfortable carrying system on it?

Sew on another nylon strap. Add some patches on the inside and outside of the bag. It is easy to find dry bags with straps for a reasonable price now at places like Sierra Trading  Post.  If you have one larger dry bag with good straps you can probably put your existing one on top for a portage. It usually takes more than one dry bag for a canoe trip.
