These semi-rimless shades by Oxigen are made for men who are active and want a pair of shades that will be reliable and hold up to active use. The frame is made of plastic, designed to be lightweight and comfortable, but also strong and able to hold its shape. The arms are curved with various patterns and a textured section around the ear for better grip. The Oxigen logo is displayed on the side of the arms. The lenses are rounded rectangles with a smoke or mirror finish that protects your eyes.
