Our products are crafted for durability and everyday adventure using genuine BioThane®. They should be matched to your dog's size and activity level. They are not rated to specific pull or load thresholds, so selecting the right product for your dog is essential.


Due to lighting and monitor differences, actual colors may vary slightly from what appears online.

We recommend washing your BioThane® gear by hand with mild soap and water, and then drying it with a soft cloth. Please keep in mind that brass hardware will naturally tarnish (develop a patina) over time; regularly polishing or cleaning the hardware will help minimize this process. Our nickel-plated, chrome-plated, and matte black hardware may show wear and tear over time; however, this is normal and does not compromise the hardware's integrity. To clean your hardware, we recommend washing it with mild soap and water, then drying it with a soft cloth.

Important Note: Please ensure that all hardware is thoroughly dried 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 dirt and grime, please note that it is not completely stain-proof in all circumstances. Regular cleaning is recommended to keep your BioThane® gear looking new.

Not all waterproof material is created equal; we use only Genuine BioThane® on every product we make.

BioThane® is a polymer-coated webbing that performs like leather without the drawbacks. It's waterproof, won't mold or mildew, and resists most common pet and outdoor odors. A quick rinse is all it takes to clean. BioThane® is manufactured in the USA.

While BioThane® repels most dirt and grime, it is not completely stain-proof in all circumstances. Regular cleaning with mild soap and water will keep your gear looking its best.

BioThane Leash & Collar FAQ

Which hardware finish should I choose?

For Collars: Solid Brass stays looking like new with regular cleaning. Silver (Nickel-Plated) and Matte Black (Zinc Alloy) buckles are plated finishes that stay sharp with minimal upkeep. Nickel-Plated and Matte Black buckles are lighter weight.

For Leashes: Solid Brass stays looking like new with regular cleaning. Silver (Chrome-plated) and Matte Black (Zinc Alloy) trigger snaps are plated finishes that stay sharp with minimal upkeep. Aluminum and Matte Black carabiners are extremely resistant to corrosion and wear and are very light.

Heavy use on plated finishes may affect appearance over time, but won't impact performance. Rinse and dry all hardware thoroughly after any exposure to water.

Can I customize the colors?

Yes — choose your collar and leash colors independently to create your own combination.

Are BioThane leashes and collars waterproof?

Yes, 100% waterproof. Won't absorb water, and resists most pet and outdoor odors. Perfect for beach trips, river walks, and rainy days.

What size collar do I need?

Measure your dog's neck at the base. Take your dog's coat into consideration. You should be able to slip 1–2 fingers between the collar and neck. If between sizes, size up. Refer to our size guide

Do I need to condition my BioThane leash and collar? 

No. Unlike leather, BioThane requires no conditioning, oiling, or special treatment. Just rinse with water and wipe dry — that's it.
