I have had many expensive sunglasses over the years, several Oakleys, Maui Jims, other Costa’s, these are by far the best. I bought them mainly as fishing glasses, polorized with green glass mirrored lenses, however I have been using them for driving as well, they are excellent as they make colors more vivid, so clear and reduce the sun glare to almost nothing. I have never had polorized glasses cover as much area under water as these do with so much clarity. I know my sunglasses and would give these five stars.
I was a Ray-Ban aviator guy for decades and then I bought a pair of these Serengeti’s. WOW! like another aviator reviewer said, they’re like x-ray vision in the sky. I live in a place that has a lot of clouds and overcast and with these I can pick out other airplanes that I’m sure I couldn’t do with my old ‘bans. But the best is, these weigh practically nothing in comparison. and this Medium fit is perfect. These glasses are my standard now.Love these glasses, so cute! Quality seems pretty good, glasses feel sturdy.
