?Night Safety? Reflective lines are added to both the pockets and leash to ensure visibility and safety during nighttime use. ?Shock-absorbing Spring Rope?If you have a large dog, you need a leash that can absorb impact and control it without interrupting your pace. The spring rope and plated hook can absorb all shocks and vibrations from dogs weighing up to 100kg/220lbs, helping to reduce back pressure and the risk of injury. Our leash can stretch up to 179cm/70.5". ?Dual Handle?Complete control is crucial for your dog. The control handle on the front end allows you to firmly grasp your dog when necessary, preventing fights and other accidents between dogs. ?Multi-scene Use?1. Can be connected to the waist bag as a hands-free leash. 2. Can be used separately as a handheld bag. 3. Can be tied to a pole or tree stump. 4.

Can also be used as a sports waist bag. ?New Design - Lightweight Version?Waist bag + leash weighing only 320g/0.7lb, making the waist protection more lightweight.
