Feel the G-Forces on REVOLUTION! It provides unparalleled spinning fun for 2 riders. Lie down or sit it up, either way, you’re going to spin like there’s no tomorrow! The strategically placed inflatable topside center fin and 2 leg holding fins keep you from getting thrown by centrifugal force. If you prefer not to spin, just thread the tow rope through the No Spin Strap. At the center of the bottom you’ll find the tow point, a super strong 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 30g 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).
