I have a pair of Oakley Half-Jackets that I like very much. They also have interchangable lenses, and the frames "stick" to your face when you begin sweating -- no bouncing around. Unlike the Tifosis TheActiveWatcher recommends, however, I would not necessarily characterize the Half-Jackets as reasonably priced (at least not from an Oakley store). You can find more reasonable prices on eBay, but it's a riskier market there....

I have Oakley Flak Jackets and love them. Similar to the Half Jacket but more streamlined and better lenses. Cost me about $200 but worth every penny.
I use them for everyday wear, running, xc skiing, kayaking etc.
Great alround pair of glasses Id say go try on as many pairs as you can find though cause everyone has a different shaped face and wants or needs.
