Contoured to fit the shape of a horse's back, this pad features wither relief cutout with a sewn-on leather spine running the full length of the pad to reduce stress and provide long-lasting reinforcement. High impact gel inserts run the length of the pad, positioned under the saddle's bars. The gel disperses energy and stress. Bottom layer is 1/4" of the most pure wool felt available. This high density, anti-microbial layer pulls heat & moisture away from your horse's back while adding an extra layer of durability. 3/4" thick, measures 31" x 30".
