Start by fastening the waist clip. The belt should sit comfortably over your hips. The more weight you carry, the tighter the belt should sit to prevent it from bouncing.
Below the main pocket, you find the rail system for the leg straps. Fasten the strap to your preferred attachment point, then attach the hook at the loop in front of the belt.
At last, adjust the front piece. The recommended distance between your body and the carabiner is at least 15 centimeters/6 inches. This allows the carabiner to follow your dog’s movements and distribute pressure evenly. The front piece can also be removed completely if you are running without your dog attached.
