This running belt is super-light and designed for optimal performance. The unique construction helps to take the strain of the lower back and promotes good running technique. We involved elite canicross athletes in developing the CaniX belt, and the result is a favorite for multiple World champion canicrosser Ben Robinson, and several other top athletes. The belt weighs only 280 grams and is very durable. Technical and breathable materials ensure running comfort in any temperature. The CaniX belt comes with a locking carabiner as a standard attachment point for your dog's bungee leash. The carabiner moves on a loop in front. It follows your teammate's movements, providing equal pressure on your hips even if the dog is pulling off-center. With this setup, it is easier to maintain balance and contact with your dog, also in turns. CaniX Belt has loads of adjustment possibilities, to fit a wide variety of body shapes. The running belt comes in two sizes, Small and Medium. There is a pocket on the backside, large enough to hold most smartphones. Reflective details on the belt help you to stay visible in the dark.
