Martingale in tanned leather that prevents the upward  movement of the horse's head, acting directly on the mouth by means of  the reins passing through the ring placed at the end of the fork.
The  reins must be used with stoppers, otherwise the martingale can slide  forward and get caught on the bit ring, blocking the horse's head and  risking to make it fall.
Each strap or buckle is made of stainless steel.
