It’s the most versatile bag you can own – a full-length waterproof bag to protect gear from rain, sea spray and submersion … a full-length breathable mesh bag for wet gear … or a combination of both. The roll-top closure and welded seams provide a watertight seal. The air-purge valve allows easy compression. The exterior mesh drying compartment expands as you need it. Made from lightweight, TPU-impregnated nylon.
