A wild ride for up to 2 thrill seekers, the G-Force towable tube is designed with topside stabilizer fins to help defy centrifugal force. Four deluxe nylon-wrapped handles with neoprene knuckle guards provide a sure and comfortable grip. The G-Force towable has a tough heavy-gauge virgin PVC bladder that’s fully covered with a durable double-stitched nylon cover. G-Force comes equipped with a heavy-duty Kwik-Connect for easy and secure hook-ups and a speed safety valve for inflation/deflation convenience. 64″ x 60″ deflated. The Speed Safety Valve is a simple, easy-to-use valve that’s welded directly to the towable bladder. It opens for inflation when pushed in. The Speed Safety Valve cannot be replaced. If it becomes detached from the bladder, then you’ll need to replace the whole bladder.
