Start off by saying these are some awsome looking shades, nice material. But i wish they made a pair with some darker lenses in them, instead of the light shaded ones. These still block out the sun good though. The reason for the mediocre score is because, four days after buying these in florida, i noticed that the left lense was really loose. When i got back to colorado, i exchanged them and it took 4 different pairs to find one that didnt have a noticeable wobble. All of them had a left lense that wasnt secure, the one i change my old pair with still has one, but these are awsome glasses.
