Tendon protection in impact-resistant plastic with an interior in perforated Air-cycle-prene that lets air and heat through. Lined with bamboo closest to the horse's legs, which prevents chafing and transports moisture away from the skin. Ventilation holes at the back of the shell allow excess heat to escape. Moulded shell with extra reinforcement in vulnerable areas for increased protection. Cutaway back for greater freedom of movement. Wide elastic snap fastener.
