Wife Loves Them

Got these for my wife and she loved them. They weren't really her "style" but once she put them on she was very pleased with the change up.

Great Pair!

I got these for my boyfriend for his first Knockaround pair. He loved them so much I had to order another pair in a different color combination for him!

Loves these

I love all the Knockarounds I bought. Best thing I’ve bought in a while in regards to value for money and that I love wearing. Also I now have sunglasses in all the places I need them instead of hunting down my one previous pair

Perfect sunnies!

Absolutely perfect in every way. Hubby appreciates the larger/wider frame for his “large” face and the colors were perfect. Had a similar pair in a different frame and sent them back to exchange for these. The process was simple and seamless. And the sunnies are EXACTLY what he was looking for!
