Tough. Light. Waterproof. Floats. What more could you ask for in a bag? How about an air expelling design for compact packing? These bags have a special waterproof, air permeable fabric at the base that releases extra air inside the bag. No vents or compression straps – just roll the bag down, close the buckle, and you’ve just saved space and weight. Double-stitched, seam taped, polyurethane-coated ultra sil nylon, so you know your important papers, iPod, cell phone, money, etc., will stay as dry as when you put them in. Plus, they’re oval instead of round, so they resist rolling when layed on their side. Strong & durable, yet soft & flexible. Colors vary.
