Was hesitant at first to buy these, was afraid they’d be fake, but after getting them shipped to me quickly and inspecting they are genuine costa’s. Fit great, even better price! More than satisfied with the seller, and would highly recommend buying these frames.For me, I wanted sunglasses I could comfortably fish in and wear around town or while driving. I think they look and for great. They are slightly on the heavy side due to the glass lenses, and not nearly as comfortable as MJ’s but much better quality than Oakley’s, so there’s where they’re at in my opinion.I got the black frames with blue mirror glass lenses and wear them everywhere. Also, I really like the spring hinges on this model, very handy when moving from your face to the top of your head with out feeling like you’re stretching them out. It also helps them feel more snug when wearing them out.I did notice that the glass lenses were more “brown” when looking through them compared to the plastic lense, which looked more grey. Highly recommend!
