Our BioThane® Everest Adjustable Martingale collar comes complete with a martingale chain and an adjustable side buckle. Crafted from Beta BioThane®, the collar body is 1" wide with 3/4" accent pieces and a 3/4" buckle to reduce hardware bulk. Beta Biothane is a coated webbing that is water-proof, stink-proof, super durable, stronger and lighter than leather. Made in the USA, BioThane® Beta has a soft, easy-to-grip feel and is very pliable even in the coldest weather. Easy to clean with soap and water and antimicrobial, so no need to worry about even the dirtiest outdoor activities with your dog. Collars pictured show a two-tone look, so color options are plentiful!
