A duffel which takes military-inspired toughness to whole new levels — or even beneath them — Madwater Duffels are fully waterproof to an impressive 15-feet. The American-made body is crafted from double-coated commercial grade polyurethane, backed by waterproof zippers and nylon webbing handles with enough length to double as backpack straps. As durable and as practical as waterproof bag comes.
