AIRHEAD REVOLUTION provides unparalleled spinning fun for 2 riders. Lie down or sit up, either way, you?re going to spin like there?s no tomorrow! The strategically placed inflatable topside divider fin and 2 leg holding fins keep you from getting thrown off by centrifugal force. You?re too old to enjoy spinning? Just thread the tow rope through the No Spin Strap and enjoy a mild ride. At the center of the bottom you?ll find the tow point, a heavy duty stainless steel swivel. It?s held in place with Kevlar strapping sewn to multiple layers of heavy gage tarpaulin material. REVOLUTION is built to last; a rugged 840 denier nylon cover fully covers the high impact 30 gauge K80 PVC bladder inside. Two neoprene panels and 8 handles with neoprene knuckle guards contribute to a comfortable ride. A Boston valve provides quick inflation and deflation. 80 in. (deflated).
