A hackamore is designed to exert pressure on the bridge of the nose and under the chin of the horse's head. The headstall of a hackamore also applies pressure to the horse's head behind the ears (poll). The bosal is a breaking hackamore made of a headstall and bosal, or noseband. Bosal hackamores are used in training young horses in the stock seat discipline.
