Head out on a sunny day wearing the Oakley Flak Beta Sunglasses for optical clarity, UV protection, and comfort through any active pursuit you get after. When you're cycling, the wide peripheral view and half frame design allow you to confidently take on any route. If you're road or trail running, the Unobtainium nosepads deliver a secure fit as they increase their grip when wet. And when you find yourself hiking or backpacking, their lightweight and durable frames will keep you comfortable through the miles.
