There is no outside binding. This Patented Draft Horse Cinch features open weave breathable PVC which helps the area under the girth stay cool. It will not absorb sweat! Others have copied this cinch but cannot use the patented mesh interior that allows air and heat to pass through the cinch. High quality stainless steel hardware is used throughout. Two solid Stainless Steel D's at the center for easy attachment of training aids. This western cinch will not chafe or scald or gall. It is easy to clean, just hose off. It will dry in minutes. The Patented Shenandoah Cinch does not hold bacteria like leather, fleece or fabric cinches.
