CATAGO's FIR-Tech shoulder guard is made of a soft and stretchy fabric that protects your horse from rubbing. The shoulder guard has woven ceramic particles that reflect the horse's own body heat, resulting in increased blood flow, tension in the horse's shoulder area is alleviated and muscles are kept soft and flexible. As something new, this shoulder guard has a pressure-relieving pad of memory foam at the withers, which provides extra protection for the horse in a vulnerable area.
