Engineered to provide outstanding back protection and shock absorbency, Cashel Cushion pads are made with a unique closed cell foam originally designed for the aerospace industry for it's unique ability to distribute weight and absorb shock. Cashel Cushions will not collapse or absorb moisture and bacteria the way open cell foam pads do, nor will they retain heat or add unnecessary weight the way liquid gel pads do. Extremely lightweight and conforming to your horses back, and tapered at the edges to eliminate uncomfortable ridges, allowing closer contact with your horse. They go label side up with your saddle directly on top. Recommended for use over a Navajo or felt liner. Clean with water and store on a smooth surface.
