Thin and mighty are two great adjectives to describe the new Sleepypod leash. The six-foot leash plus the convenience of a waste bag slot and utility ring is composed of high tensile strength nylon webbing and high strength, aircraft grade snap hook that will withstand more than 500 pounds of force. Tensile tested at an aeronautical lab to verify the strength. Intuitive, push-on snap hook design is beneficial for those with arthritis or hand mobility issues. Durable yet lightweight so that it won't weigh your best friend down.
