Featuring a waterproof valve that purges trapped air, our versatile 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.

• Versatile materials: Lightweight 70D polyurethane-coated nylon materials are a tougher, more resilient cousin to the ultralight BlockerLite materials. More durable and versatile, these materials are great for all-around use with confident waterproof protection.
• PurgeAir-equipped: Our unique and waterproof PurgeAir valve vents trapped air, helping the sack compress further after being sealed, and is both more durable and more reliably waterproof than waterproof/breathable fabric membranes.

• Waterproof closure: Roll-top closure features a wrinkle-free stiffening strip to ensure a secure seal when closing the dry sack.
• Durable construction: Fully welded seams result in stronger and more durably protective construction compared to sewn-and-taped seams.
• Efficient-Packing: PackTight packing system sacks feature flat-sided, rectangular shapes that nestle closely together, packing 20% more efficiently than rounded sacks for easy, space-saving organization.
