The rein system of the hackamore is called the mecate. The mecate ( or ) is a long rope, traditionally of horsehair, approximately 20–25 feet long, tied to the bosal in a specialized manner that adjusts the fit of the bosal around the muzzle of the horse, and creates both a looped rein and a long free end that can be used for a number of purposes. When a rider is mounted, the free end is coiled and attached to the saddle. When the rider is dismounted, the mecate is not used to tie the horse to a solid object, but rather is used as a lead rope and a form of longe line as needed.
