In addition, it is odor-proof and water-resistant, and above all - made to last. The vibrant colors are eye-catching, on-trend, and beautiful for both you & your four-legged friend.

2.) Choose your secondary color (The color for the snaps and O-Ring)

We recommend handwashing your Biothane gear with mild soap and water and drying it with a soft cloth. Please keep in mind that brass hardware will tarnish (patina) over time, regularly polishing/cleaning the hardware will minimize tarnishing. Our gold (brass plated) and matte black hardware can show wear and tear over time, however, this is normal and does not affect the integrity of the hardware. To clean the brass plated and matte black hardware, we recommend washing with mild soap and water and drying with a soft cloth.

Important Note: Please make sure to always thoroughly dry all hardware after use in any water, especially salt water. This will help to prevent the hardware from rusting.

While Biothane is incredibly versatile and repels MOST of the dirt and grime it comes across, please note that it is not completely stain-proof in all circumstances. Regular cleaning is recommended to keep your Biothane gear looking new.

Why Biothane?

We only use Genuine BioThane® on our leashes and collars. BioThane is a Polymer coated webbing that is durable, waterproof, and easy to clean. BioThane® rinses clean in seconds, will not mold or mildew, and will not absorb odors. BioThane® is manufactured in the USA.
