1 Inch Quick Release Two Tone Fi Compatible Collar


  • Collar width is 1″.
  • Smallest size option fits a 15″ neck.
  • Collar contains both tongue buckle (so that it’s adjustable) and a quick release buckle.
  • Collars are interchangeable! All you need is 1 set of Fi Links and you can change out the colors as you please. So go ahead and purchase all your favorite colors while only paying that pesky $12 Fi Link charge once.
  • If you don’t have a set of Fi Links, you can add them to this product below.
  • Collar does not include Fi Module – to purchase the module, visit https://tryfi.com/ to purchase.


The adventurous dog deserves an adventurous collar. Our Fi compatible BioThane collars are just that! With BioThane that holds up to runs, wrestles, swims, and more without collecting smells or stains.


BioThane is easy to clean with just some water, soap, and maybe a sponge. And while your dog may love rolling in stinky things, your collar won’t hold on to the stench!


Due to the custom nature of our products, items cannot be returned – please measure appropriately to ensure the perfect fit.

This is the color of the tabs that surround the Fi module.
Please measure your dog's neck in inches and report the number here. Smallest size is 15 inches.
  • Options Price: $0.00
  • Product Price: $38.00
  • Total: $0.00
  • Interchangeable Design

    Our Fi Link loop system allows you to slide Fi links in and out of the collar. This means you can use multiple Pimped Out Pup Fi compatible collars with just a single set of Fi Links.

  • Size Options

    Our BioThane Fi Compatible Collars come in 2 different widths; 1" and 3/4". Our 3/4" widths still have 1" loop systems to properly fit the Fi Links and module but have smaller hardware that works better for smaller dogs.

  • Ecollar Addition

    Like to use your Fi Collar for an Ecollar too? Look up the width you need for your Ecollar and purchase the appropriate Fi collar (1" or 3/4" width), then tell us in the comments that you want to add an Eollar.

  • Stink Free

    BioThane is easy to wash with just some water and mild soap. Plus, it doesn't hold on to smells! Dog peed on your leash? Simply wash it off and keep on going!
