BioFit Fleece Bottom Pad 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. Same 7/8” quality wool blend as the original BioFit but backed with an ultra soft moisture wicking fleece bottom that offers added shock absorption and comfort. Works well for very high withers or older horses with a diminishing topline, bridging problem. 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. 31"x 32".
