That is what I am hoping. Hang it from the frame, zip it shut, water goes through it, beer doesn't leave!
My main concern was if the drop bag could hold the weight of a virtual solid mass of full 12 oz. cans in a whitewater, environment. Once afloat, the physics improves with the transfer of mass from cans to Captain to River.
If your bag, full of beer, did not break on a moderate 4-6 day float, class III-IV, I want one.
