HO Formula 2 tube. Moderate wear but all seams are in tact and there are no leaks. All inner tubes have been replaced recently and there are 3 brand new replacement tubes for the seats. 2 extra Boston values included. Adding a pump to the deal also. This is a perfect tube, especially for smaller children who want the security of feeling protected. I just sold my boat and I'm now selling all my gear. $150. Message or text me please. 801-231-5430. Thank you!
