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 weight distribution and shock reduction. They will not collapse or absorb moisture and bacteria the way open cell foam pads do, nor with they retain heat or add unnecessary weight the way liquid gel pads do. Extremely lightweight and conforming to your horse's back, Cashel Cushions will help relieve pressure points and are tapered at the edge 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, felt liner, or quilted pad. Clean with water and store on a smooth surface.
