Oakley Half Jackets, red and white with red polarized lenses. So comfortable, they're limited make with GB flag in the logo on the sides. I thought they were going to be fake when I ordered them, turned out genuine.
But everyone else at my club has Oakley Jawbones(?), the ones with full frames around the lenses in Livestrong colours. Mostly because it matches our kit, and they were bought before all this Armstrong accusations.
Either way, Oakley are by far the best lenses and frames that I have ever worn, comfort and durability. My dad has some from before I was born (I'm in my late teens), and they're only just beginning to show signs of weakness.
