AIRHEAD SWITCH BACK 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 SWITCH BACK! This deluxe towable slides effortlessly across the wake. There are plenty of boarding straps for re-boarding from the water. SWITCH BACK features 2 heavy gauge PVC bladders and a rugged double stitched nylon cover to ensure long service. Inflation and deflation is easy with the two patented Speed Safety Valves. Size: 88 in. x 70 in. (deflated).
