It rides a lot like the old inner tube you remember, but the Connelly Spin Cycle Inflatable offers several upgrades over the classic. Most obviously, the Speed Valve for inflation makes filling the heavy duty bladder quicker and easier, and the included adapter makes it easy to find a pump to do most of the work for you. The Nylon cover adds comfort by putting a barrier between you and the heavy duty tube, and padded handles make it easy to hold on without banging your knuckles.
