The Mercenary was introduced as the lifestyle version of Oakley's most popular sport frame, the Oakley Flak 2.0 XL. This versatile frame has enough sport features to keep you covered no matter what you encounter on your next adventure. Unobtanium nosepads and temples keep the frame aligned and in place for all-day comfort. Oakley's proprietary lens material, O Matter, is both lightweight and highly impact resistant. The extended, semi-rimless lenses are available with PRIZM lens technology to boost contrast, making it easier to pick up on details so you don't miss a thing.
