HO Molecule Tube Designed for up to 3 riders, this tube is guaranteed to give you and your friends a great ride! Because of the size of the tube, HO has incorporated its own Sphere Technology which creates less drag for the tube by reducing the tubes contact on the water, giving the riders more of a faster and lively ride, and also creates less strain on the boat. If you're looking for a fun time behind the boat, the HO Molecule is a definite must have!
