Mackey Equisential Leather Running Martingale is made from high quality leather. Designed with the main purpose to control the horse’s head, stopping him from throwing his head too high and hitting the rider in the head. So when the horse’s head goes above a certain height, the martingale places pressure on the head, making it become near impossible and more difficult for the horse to raise his head any higher.
Comes in black or brown leather. Available various different sizes.
