Whether you're charging down mountain trails on your bike or pacing yourself as you run long distances, the Oakley Flak Beta Prizm Sunglasses take performance to the next level. Designed with Prizm technology, the polarized lenses eliminate glare and control light conditions for maximum contrast and visibility. The incredibly light frame is subtly flexible for enhanced comfort and durability, while the Three-Point Fit eliminates pressure points and holds the lenses in precise optical alignment. Hydrophilic nose pads get tackier when wet so your shades don't slip when you're working up a sweat on a long bike ride or run.
