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' Ã¥  quality wool blend offers superior shock absorption and protection. Contoured design molds to conform to your horse' s back for added comfort and improved saddle fit. Cut out over withers for greater gullet clearance and spine relief.
