The Essential Square Pad is anatomically designed to provide superior fit and comfort. The innovative wither relief design ensures that the pad stays in place in the gullet of the saddle, away from the spine. Durable cotton twill outside looks like new even with extensive use and washing. Slip-resistant flannel on the inside is moisture wicking and provides additional anti-slip properties. Dual-density poly-fill construction for comfort and impact protection. Generously sized, our square pad fits most sizes of saddles, even after washing. Machine wash and dry.
