The Cashel Tush Cushion makes hours in the saddle a lot less painful. Made with the same closed-cell foam as the popular Cashel Cushion saddle pads and will not collapse or give the way open-cell foam can. It will not compact or bunch up, nor hold heat. Adjustable nylon straps hold it firmly in place. It does not interfere with your seat in the saddle; it just makes it much more comfortable.
