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. Same 7/8” quality wool blend as the original BioFit®, but backed with an ultrasoft moisture wicking 100% Merino fleece bottom that offers added shock absorption and comfort. Works well for very high withers or older horses with a diminishing topline. 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"
