Check out these cool and stylish men's sports sunglasses by X-Loop that feature a pattern of metal shavings on the arms and a bold X-Loop logo at the temples. The frame is made of metal, and the arms are made of plastic, able to flex where needed, but also sturdy and rigid to hold their shape. The arms start thick and taper smoothly around a curve toward the ear. The lenses are large rounded rectangles with a dark finish that protects your eyes and your privacy.
