AIRHEAD's VIPER series is a collection of cock-pit style towable tubes. The boat hull shaped bottom is the key to the unparalleled lively and stable ride. VIPER inflatable tubes are perfect for young children who need a more secure ride or are new to water sports. The durable 30 guage bladders are completely encased in durable double-stitched nylon and the striped nylon wrap handles have neoprene knuckle guards for comfort. **INCLUDED**: AIRHEAD® 2 Rider 2 Section Tube Rope - This tube tow rope has 2 sections, giving you the option to be either 50 or 60 feet behind the boat depending on wake and water conditions. The pre-stretched UV-resistant 7/16" diameter 16-strand rope exceeds the 2,375 pound break strength required by the WSIA for 2-rider tubes. A Rope Keeper is included for convenient storage.
