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, river professionals, and bold adventurers. For added safety, the 56L sack comes with thicker coatings and a safety orange interior that doubles as a flashing orange safety feature if needed.
