Leather martingale with the aim of preventing 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 it to fall.
Each strap or buckle is adjustable so that the breastplate can be perfectly adapted to any type of horse.
