A breastcollar can have function and style, as shown with this Martin Saddlery exotic 1-inch breastcollar. First: Function. The buckles on each side allow a completely customized fit for your horse, along with the adjustable center strap. Sturdy rings at the sides and the center hold up to everyday wear and tear, as does the heavy stitiching. Next: Style. Exotic leather adds sophisticated class to your horse’s turnout, especially when paired with the small silver dots.
