The versatile, feature-laden Blocker Compression Dry Sack saves space on paddling and trail adventures. Its waterproof valve rapidly vents trapped air to ease compression, while the fully waterproof construction ensures essential contents are protected, condensed, and organized.

Features

• Versatile materials:
  Lightweight 70D polyurethane-coated nylon materials are a tougher, more resilient cousin to the ultralight BlockerLite materials. These durable and versatile materials provide confident waterproof protection for all-around use.
• Smarter compression:
  Unlike conventional systems that pull against seams, the Continuous Compression system encircles the sack to minimize seam strain, maximizing durability for dependable protection.
• PurgeAir™-equipped:
  The unique and waterproof PurgeAir valve vents trapped air, allowing the sack to compress further after sealing. This valve is more durable and reliably waterproof compared to waterproof/breathable fabric membranes.

• Waterproof closure:
  The 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.
