1/8" wool felt top. 1/2" closed cell foam bottom is antifungal and antibacterial and allows the horse's back to cool itself. Designed specifically for Reiners, to be used under a Navajo blanket top or alone. Sleek, refined design allows it to protect and support your horse while being discrete under a show blanket. Cut out over withers and contoured to fit your horse's back with a split design that allows the pad to move with the horse. Cut out in the cinch area for a closer fit to the saddle.
