Biothane is a polyester webbing with a TPU or PVC coating.  It is a durable, waterproof material that is a great alternative to leather.  Biothane is made in the USA.  

Each leash is hand made to order.  Made with solid brass bolt snaps and solid brass hammered rivets for maximum durability.
 
 
Waterproof & Easy to Clean – Unlike leather or fabric leashes, BioThane doesn’t absorb water, making it ideal for all-weather use. A simple wipe-down keeps it clean.
 
Durable & Strong – It has the look and feel of leather but is more resistant to wear and tear, making it perfect for strong dogs and active lifestyles.
 
Odor-Resistant – Since it doesn’t absorb moisture, it won’t retain odors like traditional nylon or leather leashes.
 
Flexible & Comfortable – BioThane remains soft and flexible even in cold weather, making it comfortable to hold and easy to handle.
 
Non-Toxic & Safe – Made from a polyester webbing coated with TPU or PVC, BioThane is non-toxic and safe for pets.
