Great way to keep extra gear and clothes dry in the back of the boat
"I keep clothes in this in the drift boat and it keeps everything dry sitting in waterer on the floor of the boat, and in rain. It is not going to be fully waterproof against extended full submersion just because the opening is so long and difficult to roll to seal absolutely like a proper dry bag. But for every other waterproof need on the river(other than rigging to flip) this thing is awesome."
