The Essential Square Pad from EquiFit was carefully designed to be anatomically-shaped to your horse's back. Made with a long-lasting cotton twill exterior, this pad looks fresh and clean even after long use and washing. The unique wither-relief design pulls the pad up into the gullet of the saddle, keeping it off your horse's spine. Moisture-wicking, anti-slip flannel on the inside helps keep this pad securely in place. Layered with dual-density poly-fill for impact-absorption and comfort.
