The lightest of SealLine’s packing system sacks, the SealLine BlockerLite Compression Cinch Sack is an ultralight compression stuff sack for organizing, condensing, and packing contents in backpacks and duffels, while delivering splashproof protection that defends camping and backpacking gear against light rain, splashes, and wet bags and packs. The continuous compression system encircles the sack to pack tighter and minimize seam strain. A secure draw cord closure offers speedy, hassle-free access to stuff sack contents, and a cord lock ensures that the sack stays cinched tight. Fully welded seams provide unmatched strength and durability, compared to sewn-and-taped seams, and the 20-denier silicone and polyurethane-coated nylon delivers water resistance while barely tipping the scale. Unlike traditional, rounded stuff sacks, the SealLine BlockerLite Compression Cinch Sack is shaped like a rectangle with flat sides that nestle closely together and pack 20 percent more efficiently, for space-saving organization. Available in three sizes for building out the perfect packing system for backpacking, camping, boating, expeditions, and travel: 5-liter (305 cubic inches) measures 3.5 x 6.4 x 11.8 inches and weighs 2 ounces; 10-liter (610 cubic inches) measures 4.3 x 8.2 x 14.1 inches and weighs 2.5 ounces; 20-liter (1220 cubic inches) measures 5.5 x 10.4 x 18.8 inches and weighs 3.2 ounces. Manufacturer’s limited lifetime warranty. Made in the USA.
