Big Kahuna, as well as looking extremely cool <img src="cool.gif" border="0"> , Oakley has some of the best lenses and many to choose from. I have a pair of A-wires (not A-"frames", rho <img src="rolleyes.gif" border="0"> ), and they are great. Everywhere. On the Oakley website there is a sunglasses test, from PrivatePilot 2002, and Oakley is named the best in both polarised and normal sunglasses category.
This is the winner:

Off course we all know where the coolest "sunglasses" are! They are attached to a fighterpilot's helmet...
