Contoured one inch inch thick wool felt with XRD protective inserts. XRD technology is all about action and impact! Absorbing up to 90% of energy at high speed impact. The insert material is thin, lightweight and breathable not to add any additional weight to the saddle pad but when impact occurs it creates a comfortable protective shell that shields the body from impact force. XRD inserts are strategically placed inside the saddle pad, offering the greatest comfort and protection to your horse. Top grain wear leathers. Size: 31" x 28" x 1"
