Ive got 6 moose hunt float trips under my belt, and Ive learned my lessons on dry bags. The first year , I used a northface duffel that I believed to be a dry bag, that was sold to me as being such. It wasnt. It was torrential downpour to start the trip, and the raft had a wet bottom. All my gear was completely submerged, food, everything. My own inexperience, my own fault. The first few days were not the most fun, but thats why I use a synthetic bag on a river trip. Since then, Ive invested in Watershed bags, and keep my sleeping bag in a dry compression bag, extra clothes too. The Watershed bags are fantastic, the rubber zip lock closure can be a pain on really cold mornings with cold hands, but they are durable, and have a bunch of different sizes. I use a duffel back back and the largest duffel they have to put all other food and gear into, makes it easy to get on bush planes. They also make a rifle dry bag thats pretty sweet, if your gun has a wood stock.
