Mecate rein

The mecate (/məˈkɑːtiː/ or less anglicized /məˈkɑːteɪ/; Spanish pronunciation: [meˈkate]) is the rein system of the bosal style hackamore used to train young horses.

Then, the loose end is wrapped two or more times in front of the rein loop until the bosal is the proper diameter to fit the horse, and secured with another clove hitch, leaving the long lead rein end coming out the bottom of the bosal, secured by the last wrap.

Sometimes, a heavy bosal is stabilized by the addition of a fiador, which is a type of throatlatch usually made of thin cotton rope.

Sometimes considered an adaptation of the California tradition to the Texas tradition, it allows the rider to hold on to the horse while on the ground, but the drawback to the design is that the lead rein comes off of one side of the bit, creating an imbalance in the horse's mouth.

To balance the lead rein, some users add a large tassle on the bight off the other side of the bit.
