(Impact Gel Saddle Pad) Designed to fit the "round" or "mutton-backed" horse, reducing inconsistencies in the fit of the saddle to the horse’s back. 1/2" thick wool/polyester felt blend is combined with the exclusive Impact Gel. Impact Gel is over twice as effective in reducing impact as any other substance tested, yet provides dramatic dimensional stability. Large vent holes throughout the top of the pad reduce heat build up and rigging cut outs reduce bulk under fenders. Leather wear leathers.
