We call this the Buster collar because the pattern was given to us by Buster McLaury, horseman and cowboy. Made from heavy harness leather or skirting leather, this collar fastens with straps that pass through the gullet of your saddle. The gullet straps are included. The idea behind this is to have a breast collar that does not restrict movement of the horse by pulling on the points of the shoulder. It can be made slickout (shown) or roughout.
