Sea to Summit Evac Lightweight Compression Dry Bag

13-liter roll-top/compression strap dry bag with an air-permeable base—air can be pushed out, but water can’t get in—and four straps for even compression of gear for backpacking, camping, and water sports Manufactured from bluesign-approved lightweight PU-coated 70D nylon, with a valve-free expelling 40D nylon air permeable/waterproof base; 10,000mm waterhead (the higher the waterhead rating, the more waterproof the fabric) Reinforced waterproof seams are double-stitched, and tape sealed; light-reflecting white interior for better visibility of bag contents Low-profile, streamlined shape saves space, and oval base resists rolling; patent-pending field repair buckle can be replaced in seconds; compression straps have two ladderlock and two side-release buckles 13-liter compression dry bag measures 8.7 x 8 x 17.6 inches when closed, and weighs 0.3 pounds; volume is 13 liters (with closure rolled three times)
