You may not be representing the red, white, and blue on the big stage this summer, but you can still show your support while enjoying superior performance with the Oakley Team USA Flak 2. 0 XL Sunglasses. Enhanced lens coverage and a sporty wrap make these lightweight shades ideal for cycling and running, and High Definition Optics ensure you'll be able to see the road ahead clearly. O Matter material keeps the frames incredibly lightweight, without sacrificing durability, and Oakley's patented High Definition Optics provide superior optical clarity and razor sharp vision at every angle. Hydrophilic Unobtanium nose and temple pads get tackier when wet, which means the more you sweat or the harder it rains, the better the shades stay on your face. The XL edition offers enhanced lens coverage and specialized lens curvature for protection against sun, wind, and impact Proposition 65 Warning for California Consumers: This product contains chemicals known to the State of California to cause cancer andor birth defects or other reproductive harm.
