Sealline’s lightest compression sack, the new splashproof and ultralight BlockerLite Compression Cinch Sack not only saves space, it saves weight for thru-hikers and gram counters. The ultra-convenient draw cord opening makes it fast and easy to access, all while supplying a high level of splashproof protection. Features Ultralight: Featherweight 20D silicone- and polyurethane-coated nylon delivers splashproof defense 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. Securable, easy access: Draw cord closure supplies speedy, hassle-free access to contents while the lockable cord lock ensures the sack stays cinched tight. 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.
