Behold the latest addition to the HO Sphere Tech line of tubes, the monstrous ION! Never before has a tube this large been possible without placing incredible strain on your boat. The 4-person Ion uses HO Sphere Technology to suspend the deck of the tube off the water leaving the spheres as the sole point of contact. This dramatically reduces surface area on the water making the ION the fastest big tube out there. The new four ball design takes the rider weight and distributes that force equally over the entire tube resulting in a tube that is more stable and less likely to sag in the center. With sphere tech tubes taking over the waterways, get yours fast before you are left out in the cold.
