BioThane is a leather-like material which was developed in the USA. Because of its composition (a polyester core with PVC coating), it’s a highly durable and long-lasting material. BioThane is 100% waterproof. Although extremely durable, it’s also soft and elastic (including in the cold). In addition, it’s stain-resistant, easy to clean and doesn’t need special care (unlike a leather collar, for example). We always use authentic BioThane with a matte coating for our Nelly&Dodo collars. The material has good grip and is pleasant to the touch.
Under normal conditions a BioThane collar will last longer than a nylon or leather collar.
