The careful engineering of the Cashel Tush Cushion puts relief only where you need it, allowing you to ride comfortably for hours. Your Tush Cusion is made with the same popular closed-cell foam as the Cashel Cushion saddle pads, which will not collapse the way open-cell foam does. It will not compact or bunch up like fleece seat savers, nor absorb and hold heat the way a gel pad will. Adjustable nylon straps hold your Tush Cushion firmly in place, preventing the sliding and shifting problem experienced with other seat savers. Designed to fit most English saddles.
