These rectangular sunglasses for men are made by Oxigen and feature a boxy look and feel that make you look studious and hip at the same time. The frame is metal, and the arms are plastic, flexible where needed, but rigid and strong enough for daily use. The arms start thick and taper to the sharply curved earpieces. The Oxigen logo is seen on the arms. The lenses are rounded rectangles that have a dark finish to protect your eyes.
