Air Force knows how to design a cool pair of aviator sunglasses, and these shades for men and women are unique and attractive. The lenses flow together in the middle in the shield style, a rarity in aviator glasses. The lens shape and the dark finish combine to protect your eyes. The frame is made of metal, flexible and lightweight for a comfortable fit. The arms are straight and thin and flow back to the curved ear that has an added plastic sleeve for better grip.
