Strong? Yes. Sustainable? Yes. Casually stylish. Absolutely! Waxed canvas harnesses get even better with age. They develop the look of distressed leather and can be re-waxed when needed to stay water resistant. They are handmade with a cotton canvas permeated with a non-toxic wax. The aluminum, quick release buckle along with the solid brass hardware add to the style and strength of our harnesses. Crafted in the U.S.A, we stand behind our products, so if need be, we'll repair for free.
