Turbo Blast is not only a head turner, it is one hot riding tube! The double open top tube has a rugged double stitched 840-denier nylon cover with 2 self-draining floor vents. The 30-gauge virgin PVC bladder is equipped with a Boston valve, the ultimate in inflating and deflating convenience. Four deluxe handles with neoprene knuckle guards ensure a comfortable grip. You'll really appreciate the heavy-duty Kwik-Connect every time you hook-up your tow rope.
