Made from strong, high-quality nylon webbing that is abrasion resistant and carefully stitched at the seams for long-lasting performance. The trademarked “Bucklebone” side release clip has been developed to be the strongest side-release buckle on any dog collar and ensures the collar stays secure during walks, while its design makes it easy to put on and take off. The collar also features a fully welded stainless-steel D-ring that won't rust or corrode, even in saltwater. Fabric content: 100% nylon webbing.
