You've just got to check out my cycling shades that I got for riding. My co-workers husband reps for Axley and I got a pair for my birthday (along with some extra lenses and a kicking cool new hat). I've been out with them on a few times now and I'm very happy with them. They are light weight and keep the wind completely out of my eyes which is totally huge for when you are screaming along.
Of course they look hella sexy too. Check'em out at http://www.axleyusa.com/glasses/#
