Adjustment strap refits any breast collar that rides too low across the horse’s shoulders, limiting his mobility; or too high at the throat, cutting off his wind. Just snap into the rings located between the breast collar and the tugs that attach to the saddle. Adjust by lifting breast collar above the points of the shoulder, lengthen tugs to allow center D-Ring to drop down. Proper adjustment provides a deep V-shaped breast collar for enhanced fit and performance.
