Rectangular sunglasses with a thin frame that features a double-bridge construction, these nice shades by X-Loop are for men who want a simple look that still stands out in a crowd. The frame is made of metal, and the arms are made of plastic -- a combination that allows the shades to bend and flex but stay rigid and durable as needed. The arms are thin with a flare in the middle, and the X-Loop logo is shown on the side. The rectangular lenses offer optimal eye protection.
