The elastic martingale attachment prevents the horse from putting its head up by indirect action on the horse's mouth through the reins. This product is less strong than the classic and bib martingale attachments, as the elastic softens the action when the horse puts its head right up. This item is for more sensitive horses. This martingale can be adjusted with a number of holes, and has a strap specially designed for any excess leather flap. This high quality product is made of both elastic and vegetable-dyed leather.
