Jump'In Small cheek leather Hackamore (Havana)Composition: Hackamore with a leather nose part, stainless steel small cheeks, and a leather curb chain. Effect: the Hackamore has a lever action on the bridge of the nose and the mandibles only. It will not have any action on the inside of the mouth. It is great for horses that don't tolerate bit contact in their mouth, for those that fight the rider's hand, or for those that can't be ridden with a mouthpiece. Tips: ideally used with the Jump'In
