Rugged, Lightweight, and Adventure-Ready

Adventure with total peace of mind with our waterproof, stink proof, easy to clean Fi Compatible Sport Collar (Layered Design). 

Our Fi Compatible Sport Collar is handcrafted from BioThane® and built to integrate seamlessly with the Fi Series 3/3+ GPS tracking unit (sold separately). The Layered Design keeps the Fi unit resting on top of the collar band rather than directly against your dog’s neck, offering a streamlined fit and added comfort.

Why it’s built for your adventure pup:

  • Sport hardware + Duraflex® quick-release buckle - sleek, lightweight, and secure

  • Layered design - Fi unit sits on top of the collar band (

  • Premium BioThane® - waterproof, stink-proof, flexible, and wipes clean in seconds

  • Custom look - 15+ color options with the choice to add a second accent color for Fi end link holders

  • Lifetime guarantee - backed for life against material or workmanship defects

The Fi Series 3/3+ unit provides GPS + satellite tracking, fitness and sleep insights, and extended battery life — helping you track every adventure with peace of mind. Units are available at tryfi.com.

Durable, secure, and easy to clean, this collar is made to go everywhere your dog does - from daily walks to your biggest adventures.

Bruno loves it!

I needed something well made and this collar is definitely it! My husky Bruno can be a handful and his collar not only fits him perfectly but also is as strong as he is in times Bruno sees a bunny on a walk and gets crazy.

It's wonderful to hear that Bruno is loving his new collar! Thank you Gia for your awesome review helping Bruno find the perfect HTH gear!

LOVE

The last FI compatible collar I got my dog was way too heavy and thick for her (she’s 36 lbs) she was always scratching at it. This one is so lightweight, easy to clean, and the width of it is so perfect. She doesn’t even seem to notice it most of the time. And picking out the two colors is so fun.

YAY! So glad you are (both) loving your new Fi Compatible Collar! Thank you April!!! (I'm loving your color choices!)
