Featuring a waterproof valve that purges trapped air,
's 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 construction
- PurgeAir™ Equipped: The unique and waterproof PurgeAir™ valve vents trapped air, helping the sack compress further after being sealed, and is both more durable and more reliably waterpoof than waterpoof/breathable membranes
- Waterproof Closure: Roll-top closure features a wrinkle free stiffening strip to ensure a secure seal when closing the dry sack
- Secure, easy access: Draw cord closure supplies speedy, hassle free access to contents while the lockable cord ensures the sack stays shut
- Durable construction: Fully welded seams result in stronger and more durable 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
