You don't need to be riding through the Pyrenees or wearing a yellow jersey to appreciate the superior optics and performance of the Oakley TDF Jawbreaker Prizm Sunglasses. The result of a 40 year heritage of uncompromising excellence, the TDF Jawbreaker is the pinnacle of performance for athletes who demand the best. They feature a Prizm Road polarized lens, which displays the world in crisper, more vivid colors and maximizes contrast while also eliminating glare. Switchlock technology features a simple switch mechanism that allows you to quickly exchange lenses so you can stay one step ahead of changing light conditions. Stress resistant and subtly flexible O Matter keeps the frame lightweight, yet durable, and surge ports in the frame allow cooling air to flow through for comfort and fog free vision. Unobtanium earsocks and nose pads get even tackier when wet, ensuring your shades stay in place even when you're sweating bullets or riding in a rainstorm.
