(Cashel) The English Tush Cushion makes hours in the saddle less painful. Made with closed cell foam, the cushion will not compact or bunch up, nor absorb and hold heat. Adjustable nylon straps hold firmly in place, preventing the sliding and shifting problems experienced with other seat savers. Does not interfere with your balance and seat in the saddle; just helps make a more enjoyable and comfortable ride. Approximately 1/2" thick.
