The feature-laden SealLine Blocker Compression 30L Dry Sack saves space and protects your gear at the same time. Featuring the Continuous Compression system that encircles the entire sack and a waterproof PurgeAir™ valve that helps the sack compress further after being sealed, this compression dry sack is one you can count on.
70D Polyurethane-Coated Nylon
6.2 x 12 x 22.8" (16 x 30.5 x 58 cm)
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™ Valve – The unique and waterproof PurgeAir valve vents trapped air, helping the dry bag 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 waterproof 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.
