This pad is especially designed for a horse with a swayback. If your horse has bridging across the back, the space needs to be filled in to equalize the pressure and redistribute weight. This pad by Reinsman bridges the gap between the saddle and swayed back, eliminating pressure points. Especially useful for gaited and high withered horses. The pad measures 32" x 32". Maize Bottom. This pad will prove durable, easy to clean, and very comfortable for your horse. Hand wash with mild detergent, rinse, line dry.
