100% cotton top and bottom, filled with both 300 gram polyfil (on the horse side) and 15 mm pvc foam (on the saddle side). The polyfil absorbs sweat which could damage your saddle, while the foam isolates the saddle and protects it from the sweat. With wave quilt design, coordinating binding and viscose rayon rope trim. Nylon billet and girth straps. High wither relief designed to eliminate pressure on the withers. Washing instructions on sewn-in tag.
