Sharon designed this harness leather and braided nylon rope bridle especially for this bit. The draw gag aids in the suppling process at the poll, neck, shoulder and rib area. Simultaneous pressure is applied at the poll and corners of the mouth to aid in proper headset training, while also teaching pressure and release. For experienced riders and not for competition. Over use can cause too much break in the poll. Adjust to natural position, one wrinkle in the corner of the mouth.
