Traditionally, there has been very little difference between round, deck style tubes. You can buy one from any inflatable maker and they're basically all the same. That is, until now. With the addition of HO SportsÕ Shoftshell Technology, now you can tube all day without worrying about the abrasion or "tube rash" that you would get from a traditional nylon covered tube. This new technology is best thing to happen to tubes since the introduction of the nylon cover. So, grab a friend and hop aboard this 2 rider deck tube and have fun out there!
