Looking for an adjustable classic Fi compatible collar for your classy pup? Meet our Fi Compatible In-Line Classic Collar. In-Line collars use Fi certified end-links as attachments to the collar and is designed in-line with the collar. Our collars are handmade from Biothane

® which makes it waterproof, light-weight, durable and easy to clean! This collar comes equipped with our solid brass classic buckle and D-ring which makes it rust proof as well! 

All of our 

Biothane

® collars are sealed at the ends to make it truly waterproof! This style collar comes in 1" and 3/4” (3/4” only compatible for Fi Series 3) and is extremely durable and have been tested to withstand up to 750 lbs of break strength.  

Strap Keep

If you wish to add a strap keep (the piece next to the D-ring that keeps the strap in place) we currently offer white

Biothane

® or solid brass. However, with our Classic Buckle this also isn't necessary if you want to keep the collar looking seamless and minimal.

By adding a strap keep, it will add extra bulk to the collar. The choice is yours!
