Watershed Futa Stowfloat Kayak Float Bag - The Futa float bag serves two key purposes for kayakers - gear storage and flotation. Intended primarily for kayak sterns, the tapered construction allows for easy sliding in and out of your boat while filled with gear. The inflation tube is used to fill the bag with air for buoyancy in case of mishaps. The patented ZipDry seal is similar to a heavy-duty freezer bag"s zipper. It locks shut, keeping out moisture with an airtight, waterproof seal, even when submerged and under pressure. Polyurethane-coated 420-denier nylon pack cloth Kryptothane fabric offers 5 times the abrasion resistance of PVC, stays flexible in cold weather, and is more UV-stable and more environmentally friendly. Radio-frequency welding bonds the multiple layers of fabric into a single piece of material, eliminating leaks. Three external lash points and four deck attachment points keep the bag in place, and over-the-top compression straps allow the bag to be sized down to fit contents and the stern of the boat. Through intensive quality assurance, including prolonged inflation testing, Watershed produces truly waterproof bags that are guaranteed to be free of leaks. If you need bombproof dry protection for your gear, look no further.The Futa fits larger whitewater boats and touring kayaks.
