Our 6′ custom made Biothane lines are made from high quality material. Incredible breaking strength. Biothane is a unique strap that contains a nylon twill inside it. The leather type feel is soft on your hands, resistance to expanding and works excellent in wet conditions. Our brass and stainless hardware allow our leashes to survive harsh environments. Leash has multi functions, can be clipped to itself, around yourself, to itself to make it shorter and a floating ring for multi attachment options.
