Made with high-tensile, triple-thick nylon webbing with a harness leather noseband. Use as a "side pull" or "center pull" to tighten up on the nose band. It also can be attached for "no-pull" which won't tighten up on the nose. Mule halter is now available in THREE sizes: Small (new!), Regular and Large. The new small size corresponds to a standard horse halter. The regular size corresponds to a large horse halter. And the large size corresponds to an extra-large/draft horse halter.
