Shield-style sunglasses don't get any bolder than these bad boys, designed by Air Force for men. The front is all lens, and the shades are all style. The frame is made of metal, so it's flexible and lightweight, which makes for a comfortable fit. The arms are thin and straight with a plastic coating over the curved down earpieces. The lenses flow together and feature a dark finish that blocks out ultraviolet rays and offers privacy and mystery.
