The Oakley Tumbleweed 0.5 ups the ante of the customization game by allowing you to change the look of the frame just by a twist. You can literally twist and turn the temple arms and icon to show a different frame color. The body of the frame is composed of Oakley's lightweight C-5 alloy for increased strength. This semi-rimless version of the original Tumbleweed gives you a more expansive view without the bottom of the frame obstructing your vision. Unobtanium coating on the temple arms will keep the frames in place and grip-fit nosepads offer flexibility to fit the contours of your nose. You can have a fresh look every day of the week with the Oakley Tumbleweed 0.5.
