Lightweight, breathable stretch air-mesh upper material, quick and easy to put on. Adjustable size with Velcro. Cross-stitched nylon straps for optimal load distribution and protection against neck injuries. Padded buckles to prevent pressure points. Reflective elements at the neck for added safety in the dark. Includes integrated DogFinder ID. The patented curli clasp buckle sits at the top of the harness, providing maximum ease of use for the dog owner. With one click, the harness is secured and can then be attached to a leash with just one hand. This makes it easier to prepare even very active dogs for walks, as they can remain in motion while being leashed. It is made from polyoxymethylene (POM), color-coordinated with the harness, and extremely durable. The buckle can withstand pulling forces of up to 138 kg.
