Biothane never holds onto moisture, smell, or debris in the same way that fabric collars can. 

• Biothane has a coated webbing that makes it ultra strong and durable
• It's protective coating makes it water-resistant
• Our Biothane has a soft coating that has the look and feel of leather. It has a low gloss or dull appearance. It is soft and very flexible. The leather embossing gives it the leather look. It will hold its flexibility in very cold weather. 
• Washing the collar is a snap — simply use water and soap
