This is my second pair of fastlanes 4th pair of knockarounds. I still have all 4 pairs all still holding up well. I did have an issue with my first delivery but knockaround took care of it right away. Awesome company.

Pleasantly Surprised

I wanted a clean pair of sunglasses to give my well worn Ray Bans a break. Very comfortable and the optical clarity is super nice, very impressed.
