Sportsstuff Rockin Mable Inflatable 2-Rider Towable is 2 tubes in 1, ride them sitting down or kneeling! The big wrap around backrest, soft knee / seat pads and a magnitude of strategically placed handles keep you on the tube, no matter how wild the action! The front & rear Dual Tow Points are equipped with Sportsstuff’s patented aluminium Quick Connects for easy hook-ups. This tube is built to last, with a double-stitched 840 denier nylon cover and 30 gauge vinyl bladder. Inflating and deflating is a snap with the 2 patented Speed Safety Valves.
