The Ruffwear Knot-a-Leash™ is a rugged, climbing-inspired leash. The classic design uses strong, supple kernmantle rope and a secure locking carabiner. Reflective rope keeps people and dogs visible in low-light conditions. Includes a convenient accessory loop for pickup bags or small clip-on items. The leash is 11 mm diameter of rope and 5 feet long.
