I bought these after doing some research and finding all other polarized sunglasses were much more expensive. I chose the matte black finish, which basically ensured I would be at least somewhat cool. The lenses are large enough to cover my whole field of vision while still maintaining a different aviator alternative to Ray-Bans. The one thing I did find was that they tended to slide down my nose slightly, although I am told I have a very narrow head. Do yourself a favor and buy these. They're affordable, stylish, and the polarization gets rid of more glare.
