Lightweight waterproof dry sack vents trapped air to pack small.
Upgraded with our waterproof valve that purges trapped air, our versatile waterproof Blocker PurgeAir Dry Sack resists ballooning to help maximize use of space within a pack or bag. Plus, the fully waterproof construction ensures essential contents are protected.
PurgeAir-equipped: Waterproof, air-purging valve helps the sack compress further once it’s been sealed.
Waterproof closure: Roll-top closure features a wrinkle-free stiffening strip to ensure a secure seal when closing the dry sack.
