Double-bridge aviator sunglasses look simple, yet tough, and these shades by X-Loop for men are a great example of that. The frame is made of metal, lending flexibility and strength to the overall design. The arms are thin and straight and feature the X-Loop logo on the side and plastic earpieces for better grip. The lenses are large off-center ovals with a dark finish to protect your eyes from UV rays and give you privacy. Purchase these great shades in bulk for greater saving.
