Wool blend top offers superior shock absorption and protection, and resists compression and matting for a longer life. 1/2" memory foam middle layer is extremely conforming and temperature-sensitive. Continuously molds and conforms to the shape of the horse’s back then rebounds to it’s original shape when pressure is removed. Minimizes pressure points and relieves body stress. "Open cell," allowing airflow in and out of the cells and pulling sweat away from the horse. 5/8" orthopedic grade felt bottom soaks up moisture, allowing heat to dissipate away from your horse’s back. Conforms to the horse’s back while maintaining density and provides excellent shock absorption. Felt is washable and grime can be washed away as needed. Cut-out withers and contoured to fit your horse’s back with a split design that allows the pad to move with the horse; butterfly cut for closer leg contact. Designed to be used alone or with a blanket.
