Stylishly designed to sit securely on faces with a lower nose bridge, the Oakley Sylas (Low Bridge Fit) is a truly magnificent sunglass frame. The O-Matter™ construction of the frame is lightweight yet durable enough for all-day wear. The frame is also hat-compatible - the shape of the temples allows you to comfortably wear a cap with it. The model is available with Prizm™ lenses, which enhances color and contrast for a much sharper vision in bright conditions.
