Khan designed these glasses for men to be subtly cool and tough enough to stand up to any kind of treatment. The sunglasses are made of strong plastic, molded to fit comfortably, but rigid enough to hold their shape and stay looking good. The arms have a sweeping section that brings aerodynamics to mind. The Khan logo is embedded within the depression of the arm. The lenses are large and dark, rectangular in shape with rounded edges. Purchase in bulk for excellent savings.
