Spice up your Fi adventures with our biothane Fi compatible collars! They are stink proof, water proof, and stain resistant. Easy to install and you can charge the unit without having to take it off. Our quick-release buckle allows for easy on and off. Please note: This version is a fixed size and is NOT adjustable. Keep this in mind when measuring your dog's neck. Refer to our FAQ section on how to measure properly.

The collar has biothane all around the neck to prevent any irritation that can be caused by the unit and provide a more secure option. *Smaller sizes (<16") will have shorter straps holding the unit in place.

*Matte black hardware is coated and more prone to scratching.
