Patented Design The patented (US Patent No. D843,666) StretchTec Shoulder Relief Girth is the most technologically advanced girth available. Not only does it redirect the saddle's billet line to protect the shoulder from saddle impingement, but it also stretches in proportion over a horse's sternum for better breathing. Shoulder Freedom The StretchTec Shoulder Relief Girth actually changes the position and angle of the billets to prevent the saddle from interfering with the shoulder. The center of the girth is set forward to sit in the horse’s natural girth groove, while the sides attach to the billets farther back on the horse's body. This prevents the girth from pulling the saddle into the shoulder's range of motion. Better Breathing The triangular center elastic allows the StretchTec Shoulder Relief Girth to expand with the 1.5 cm chest expansion that horses experience while breathing. Its design also allows it to stretch in a more anatomically friendly way to contour better to a horse's barrel and provide even contact through the sternum area. Thoughtful Hardware Recent updates include a V-Stretch D ring design, which centers the D ring to function just like a D ring on a traditional girth.
