This pad is constructed with a 1/2" neoprene bottom, 1/4" felt center, and a durable water-repellent canvas top with rugged wear leathers. Six shim pockets are strategically placed to give you the ability to custom fit this pad to your horse by removing/adding the included 1/2" thick felt shims. The neoprene bottom not only allows for easy cleaning between rides, but also provides optimal grip for the saddle. Use this saddle pad alone or under a saddle blanket.31" x 32", 1/2"
