Westride Aurora Hazelnut BreastplateMade from cowhide leather. Basket weave detailing. Stainless steel hardware. A breastplate prevents the saddle from slipping backward. It is commonly used in show jumping, eventing, or for horses with a round conformation. Breastplates are also frequently used to attach a martingale, which prevents horses from raising their head too high. When the martingale is attached to the breastplate, it serves a dual purpose.
