I love my Oakleys. They have the best, clearest lenses of any sunglasses I've ever worn and they are light and comfortable. The Flak Jackets fit me well. The material on the temples and nosepiece is designed to get tacky when you sweat so they stay in place. I have two sets of lenses -- black Iridium polarized for most of the time, and yellow lenses for low light conditions.

The only drawback I've found is that the Iridium lenses scratch pretty easily. So I put the glasses into the fabric bag that comes with them before I put them in my purse.
