Air Force has designed a unique looking pair of sunglasses for men who embrace the boxy and somewhat nerdy look to make it cool. The frame is made of flexible metal, lighweight and comfortable. The arms are plastic with a curved look and a tapered curve at the ear. The face is squared off and the lenses are set in the thin metal frame with a double bridge and adjustable nosepieces. The lenses are dark and offer maximum privacy and protection from the sun.
