The EzyDog Neo Classic Dog Collar is super strong, super soft and built to last. Made from soft neoprene, it is very easy to clean, quick drying and waterproof. It is also non-porous, which drastically reduces any odour retention which can often be an issue with traditional collars. This neoprene is reinforced with nylon webbing for extra strength. As with all EzyDog collars, the D-Ring lead attachment is made from stainless steel which does not rust. The Neo Classic Collar also features hook and loop adjustment for simple resizing, a quick release buckle, separate ID attachment as well as reflective piping for extra visibility in low light.
