We wanted shades that eliminate the annoying glare and contrast that come with all-weather running. Enter the lightweight Oakley Fast Jacket. Its Switchlock quick release system lets you change lenses with the flick of a finger. Simply push the stainless steel button and release each lense. Then pop in your low-lights or your polarized lenses depending on weather and terrain. Minimal handling, zero hassle. Securely suspended lenses eliminate pressure that could alter the frame. And an open frame design keeps your downward view unobstructed—no trip ups here.
