With a spare metal frame, these men's sunglasses by BeOne are sleek and fit comfortably. The frame is made of metal, designed to be flexible, yet still strong and durable. The arms have a subtle pattern on the front and stay straight to the sharply curved earpieces with a plastic coating. The polarized lenses are dark and rectangular and come in a variety of color options. The face frame is thin and has a double-bridge construction above nosepieces for better fit.
