At Ghost Saddles, we pride ourselves on crafting unique, versatile, and super comfortable saddles that perfectly conform to your horse's backline. Bridging shims are generally not needed with Ghost saddles as they conform to your horse's back line. However, if you have needed to order a stiffer base and your horse has a pronounced dip to their backline, and you feel that there is too much pressure at the front AND rear of the saddle, then a bridging shim is the answer! Sold in pairs, these shims provide the perfect adjustment to ensure optimal comfort for both horse and rider. Experience the unmatched dedication of Ghost Saddles today!
