Oakley teams up with seven-time Tour de France champion Lance Armstrong to bring you the limited-edition Livestrong Radar Sunglasses. The frame and lens on these sport sunglasses fits medium to large faces, and the Livestrong Path style features Lances signature yellow on the grippy Unobtanium rubber earpieces and metal O temple emblems. Laser Livestrong logo etching on the interchangeable lenses adds another style highlight exclusive to the Livestrong line. Oakleys Polaric Ellipsoid technology maximizes peripheral vision while giving you distortion-free views throughout the lens surface. Two included nosepieces let you dial the fit of your Oakley Livestrong sunglasses for all-day comfort. Backcountry.com and Oakley will each donate 10 for a total of 20 from every pair of Livestrong sunglasses sold to the Livestrong Foundation. Because cancer sucks.
