The Kurgo Journey Air Harness is perfect for active dogs, whether they're running, hiking, camping, or just going for a walk. It's designed for comfort and ease of use, featuring lightweight, rustproof Nifco plastic quick-release buckles and a V-neck design for better movement. The padded chest reduces strain on your dog's chest and neck. For added convenience and safety, the harness has a back handle for assistance over obstacles or for better control, and reflective trim for visibility at night. This medium harness fits dogs with a neck size of 16-25 inches and a chest size of 18-28 inches. The outer fabric is highly resistant Ripstop, and the inner Mesh fabric improves air circulation. All fasteners are made of lightweight, rustproof aluminum. Kurgo is committed to quality and offers a hassle-free, lifetime warranty.
