Leather martingale with contrasting stitching, designed to limit the lifting of the horse's head thanks to direct action on the mouth via the reins that slide through a ring located at the end of the device. It is essential to use the rein olives otherwise the martingale could slide forward and catch on the mouthpiece ring, immobilizing the horse's head and increasing the risk of a fall. All straps and buckles are adjustable, ensuring a perfect breastplate fit for each horse.
