Mustang Blue Horse Contoured Felt Pad 1" felt pad with a contoured spine, withers cut-out and premium top grain wear leathers. Pressed wool is made by a process often referred to as "wet processing". Fibers are worked together by pressure, moisture, and vibration, then carded and cross-lapped to make multiple layers of material. The layers are then steamed, wetted, pressed and hardened. Pressed wool provides ultimate wicking/cooling properties and compression protection for your horse's back. Features: Size: 32" x 31" x 1"
