The Black Ice is the fastest tube around! Due to the exclusive H.O. Convex Construction this tube has a huge riding surface but a reduced contact area with the water, which makes for a super fun, quick-sliding tube. The concave riding surface also allows you to comfortably have up to three riders on the tube at a time. No expense was spared on this high end tube. Highlights include nylon webbing covered soft foam handles with neoprene knuckle guards, neoprene padding for extra riding comfort and Heavy Duty Boston Valves for easy inflation and deflation. Backed by our industry leading 1 Year Warranty, the Black Ice will keep you where you want to be on the water!
