There's no slowing you down when you're wearing Oakley Flak Beta Alternate Fit sunglasses for men. O Matter makes these shades impact-resistant and durable enough to handle your active lifestyle. The Alternate Fit offers a design that keeps the lightweight Oakley Flak frames from sliding on low nose bridges, while leaving high cheekbones mark-free. Thanks to the Unobtainium nose pads, working up a sweat won't shake off these shades. The pads also ensure the sunglasses maintain their Three-Point Fit and proper alignment, no matter how fast you go. The wrap-around design provides plenty of protection while it amps up the cool factor of the Oakley Flak Betas.
