Amazing colors and build quality

This harness is well worth the money. The colors on the harness are deep and vivid, the finish on the metal hardware goes so well with the Fi tag. Will certainly be purchasing another in the near future to switch up my pups style!


Everything is gorgeous and fit well. Excellent customer service when I had a couple of questions and Bella loves it too!
