Air Force knows how to make sunglasses, and these cool shades for men are no exception. With a squared-off look and feel, the frame is metal and plastic and is both durable and flexible to fit easily and hold its shape. The arms are straight with a cool textured pattern along the side. There is also an extra bar with a textured surface above the bridge between the lenses for extra support. The lenses are dark and are designed to protect your eyes and give you privacy.
