These cool shades by Oxigen are made for men in a semi-rimless style that lets you be active and not worry about your eyes or keeping your sunglasses on. The frame is made of plastic, designed to be rigid and withstand rough and constant use. The arms are thick and textured, and they come off the top of the frame and stay straight back to the ear. The lenses are dark and have an added nosepiece in the middle for better grip. The Oxigen logo is seen in the top corner of the left lens.
