SealLine - BlockerLite Compress

Ultralight: Featherweight 20D silicone- and polyurethane-coated nylon delivers waterproof protection while barely tipping the scales.
Smarter compression: Unlike conventional systems that pull against seams, our Continuous Compression system encircles the sack to minimize seam strain, maximizing durability for dependable 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.
