Freemotion 5.0 - Harness black/orange, size 4, neck: 6 cm/41 cm, chest: 6 cm/21.5 cm. This Freemotion harness is the result of years of experience and testing. The classic Y-shaped front allows for free shoulder movement and minimal breathing restrictions. It features a padded neck opening for optimal stability and support. The harness is specifically designed for high-pulling activities such as running, cycling, or skiing. The pulling force is evenly distributed across the dog's body without putting pressure on the spine. When leaning into the harness, the force of each step is maximized, making running together a whole new experience. All materials are durable and comfortable. The inner lining is gentle on the dog's coat. There are no hard edges, and every seam has its smooth side facing the dog's body to prevent chafing. 3M™ reflectors ensure that the dog is visible even in darkness or on cloudy days. The harness is equipped with a reflective loop. A safety light (not included) can be attached to this loop for additional visibility. Under no circumstances should the leash be attached directly to the reflective loop, as this cannot hold the dog and may lead to product failure.
