Specifically designed to support horses with muscle atrophy behind the shoulder blade. Supports the front of the saddle from collapsing in the area behind the shoulder as a result of muscle loss, ill saddle fit or conformation. Strategic wedge placement fills in the void area, offering extra support. Works well for older horses with a diminishing topline or horses with very high withers. 7/8 inch top quality wool blend offers superior shock absorption and protection. Contoured design molds to conform to your horses back for added comfort and improved saddle fit. Cut over withers for greater gullet clearance and spine relief.
