Retro & rooted, the Oakley Twoface™ is driven by the lifestyle street world of surf & skate. Twoface because of the split use of frame materials. On the one hand there's lightweight yet durable O Matter® that's been paired up with lower rims of aluminium. The result sets it away from the competitors all reaching for originality in this field. Its not just about the look though, the technology is more important and with High Definition Optics® (HDO®) on board for optical clarity Three-Point-Fit for comfort, they are just two of the proven systems that keep the Oakley brand at the top of the visionary ladder.
