Top layer is a heavy, custom weave 100% New Zealand Wool blanket which is long lasting, durable, and good looking, oil tan wear leathers. 1/2 inch memory foam middle layer is extremely conforming and temperature sensitive. It continuously molds and conforms to the shape of the back then rebounds to its original shape when pressure is removed. This minimizes pressure points and relieves body stress. It is open cell, allowing airflow through the cells and pulling sweat away from the horse. 5/8 inch orthopedic grade felt bottom soaks up moisture, allowing heat to dissipate away from your horse back. It conforms to the horse's back while maintaining density, and provides excellent shock absorption. This felt is washable so sweat and grime can be washed away as needed. Cut out through the leg area to allow close leg contact for a better feel.
