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.
