The Harmony 48 inch 3D End Float bag in nylon has all the features you're looking for in a 48 inch end bag. It has a 3D vertical nose, four isolated tie-in points, an inflation hose with a twist valve, and a rapid deflation dump valve. This is the bag of choice for shorter boats (9 ft - 12 ft) as well as whitewater tandems. This nylon float bag has all the features of the 48 inch Vinyl End Bag but is lighter and more durable. A set of two bags is almost 1 lb. lighter than the vinyl bags and noticeably lighter than competitive bags. The listed dimensions for the Harmony 48 inch 3D End Float Bag are for when the bag is inflated.
