Great durable dry bag
This is a great bag if you're looking for a durable dry bag. Its a cordura style nylon that is laminated on the inside, then the seams are sealed. I've hung it by the handle in the rain without leaks, its been thrown about in the bottom of the boat, left outside on the ground in a puddle during thunderstorms, floated through rapids, and otherwise thrown around. So far it hasn't suffered a scratch, and hasn't leaked. Unless you plan on dragging your bag through rocks, I don't see any reason to get a tougher bag. Especially when the black canyon bags weigh more than twice as much.
