The Duo is great value and an awesome two person ube. Built for aggressive use and for those who want the most bang for their buck, it can be towed in two different orientations - with the riders side-by-side, or one in front of the other - both ways work great. The center holes are round, so they are equally comfortable in both directions. They were also designed smaller than the most so they make it easier for the riders to relax and stay up off the water. The Duo is an easy call when looking for fun and value - Two is definitely more fun than one. Features: ? 2 HO Quick-connect tow attachment System ? Heavy-duty Boston Valves provide quick and easy inflation and deflation ? Full 420 Denier PU coated nylon cover ? Nylon webbing covered soft foam handles. ? Heavy-duty 26 gauge PVC Bladder
