Got Fi?  We've got your collar!  Our Biothane Fi Collar Bands are outfitted with the original Fi end pieces to make swapping your tracker out a snap.  Your collar will arrive with the end pieces secured in place - you'll just need to pop your Fi unit in and go.  No more ragged-looking, stinky nylon - Biothane can take just about anything your pup gets into - and still look pretty sweet at the end of every adventure. 

Each collar in our Biothane Fi Collection is available in a rainbow of colors - so mix and match and have some fun!
