Along side the Young Survival Coalition YSC, a non-profit working with young women affected by breast cancer, Oakley created the Enduring Breast Cancer Awareness Edition Sunglasses. Oakley donates 20 from the sale of every pair of these glasses to the YSC. In addition to supporting this cause, these sport-performance sunglasses feature interchangeable, high-definition lenses to enhance visual clarity and eliminate glare. The hydrophobic lens coating prevents water sheens and repels dust and skin oils from clouding your view. Two separate nosepiece sizes customize the fit, and the lightweight Unobtanium frame rides comfortably during your long runs or bike rides.
