From their website: "The Xstream Float Tube is the very best value in the industry. A high quality rugged boat that is known for it’s dependability. This float tube’s main bladder will support 350 lbs. It has a 14” car inner tube as a backrest and is made of 420-denier pack cloth for long life." Comes with Caddis Fins. Its a much more durable and higher quality material than you'll find with other cheaper models in the sporting goods stores. Looking to trade + Cash for a pontoon boat also, PM me with what you have. Thanks!
