M3496-KNWith thick arms and a thin frame, these shades by Khan for men are stylish in a subdued way. The sunglasses are made of both metal and plastic, strong enough to be worn during any activity, but comfortable and lightweight when worn. The arms come straight off the temples and taper around a curve to the ear. The Khan logo is displayed on the side. The lenses are curved rectangles with adjustable nosepieces for better fit.
