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.

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: 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.
