The AIRHEAD SWITCHBACK is a new and exciting 4 rider towable. Two riders sit in front with a comfortable inflatable backrest and side panels to keep them in place. The other 2 riders kneel behind them, riding chariot style. It's a totally different sensation riding in front or back, so it's like 2 tubes in 1, consequently the name SWITCHBACK. This deluxe towable slides effortlessly across the wake. Inflation and deflation is easy with the two patented Speed Safety Valves. Size: 88 in. x 70 in. (deflated).
