CORTEZ is rated 4.7 out of 5 by 78.
Rated 5 out of 5 by from swapped from the Zanes to these I got these sunglasses recently because my Zane's had some scuffs on the lenses from doing yard work. These fit a little tighter than my Zane's but I like it. They're great. I haven't had them fog up on me like my Zane's used to. Costa's are some of the best sunglasses I've owned. I have the blue mirror 580G version and wouldn't trade them for nothing. My advice though is to try them on at a local Costa dealer to see how they work for you.

Rated 2 out of 5 by from Poor quality frames , good lenses I bought these 2 weeks ago and the rubber on the frames is already coming off. I expected higher quality with a $250 price tag. Also even though they have slots cut for airflow they fog up constantly. The good part is the 580g lens is superb quality compared to anything else on the market. I will be contacting Costa for a return or replacement.
