The SealLine Blocker Cinch Dry Sack is an ultralight stuff sack for organizing and packing contents in backpacks and duffels, while delivering splashproof protection that defends gear against light rain, splashes, and wet bags and packs. A secure draw cord closure offers speedy, hassle-free access to stuff sack contents, and the 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 70-denier polyurethane-coated nylon is tough and water-resistant. Unlike traditional, rounded stuff sacks, the SealLine Blocker Cinch Dry 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 a variety of sizes and colors for building out the perfect packing system for backpacking, camping, boating, expeditions, and travel. Manufacturer’s limited lifetime warranty. Made in the USA.
