The mecate (/məˈkɑːtiː/ or less anglicized /məˈkɑːteɪ/; Spanish pronunciation: [meˈkate]) is the rein system of the bosal style hackamore used to train young horses. It is a long rope, traditionally of horsehair, approximately 20–25 feet long and up to about 3/4 inch in diameter. It is 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 dismounts, the lead rein 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 when needed.
