Looking for the burliest dry bag ever made? Available to the general public for the first time, these sacks have been engineered to line U.S. Marine Corps backpacks, providing unquestionably waterproof protection in the world’s harshest environments. Light enough for a pack liner, they’re tough enough to handle extreme abuse in or out of a backpack, making them ideal for guides, hardcore river rats and your boldest adventures. For added safety, the 56L sack comes with thicker coatings and a safety orange interior that makes things easier to find inside, while making you easier to find outside, should the need arise.
