Sea to Summit Big River Dry Pack
Best rugged waterproof carrier for serious backcountry expeditions.
This is the ultimate insurance policy for gear that absolutely cannot get wet. While the rugged, abrasion-resistant construction adds some weight compared to ultralight alternatives, the trade-off is a bombproof seal and a harness system that makes carrying heavy, dry loads surprisingly comfortable.
