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 very high withers or older horses with a diminishing topline. 7/8" quality wool blend offers superior shock absorption and protection. Cut out over withers for greater gullet clearance and spine relief. Contoured design molds to conform to your horse's back for added comfort and improved saddle fit. 31" x 32".
