Carve turns with a tube? With this steerable, 1-rider tube, simply lean in the direction you want to turn and pull on the opposite handle. The plastic fins sewn onto the side of the cover do the carving. It is so much fun that you’ll want to ride it all day long! You just might be able to, since it’s so easy to re-board with the open back design, a feature that little ones and tired adults really appreciate. Tube is fully covered with rugged 840D, double-stitched nylon cover, making it torsionally rigid to respond to rider’s commands. Tube is 48” x 50” and equipped with four deluxe nylon-covered handles with neoprene knuckle guards. Designed for 1 rider up to 170 lb.
