BioThane Reflective Leashes are perfect for walking, biking, or hiking after dark. Made with our heavy duty industrial stitching these will last forever. Like to walk in the rain? The BioThane Reflective Leash is water proof, odor proof and super easy to clean! We also offer matching collars. This is the standard weight BioThane Beta 520 so a little thinner than most of our products although still soft and pliable. The Edge Guard makes it practically impossible to separate the reflective strip from the BioThane material.
