These are not your average aviator sunglasses. Designed for men by Khan, these sunglasses have a unique flair. The frame is metal, made to be strong while still being flexible and comfortable to wear. The arms feature the Khan logo and curve sharply at the ear with plastic earpieces for better fit. The colorful revo lenses offer privacy as well as ultraviolet protection. The sunglasses are available in a wide variety of lens colors and accent colors in the dozen.
