Fashionable and also durable, these cool sunglasses for men by X-Loop are designed for sports and outdoor activities. The frame is made of strong silver plastic, and the arms feature black design add-ons. The arms curve inward for better fit on your head and curve down at the ear for better grip. The X-Loop logo is seen in black and silver on the side of the arms. The lenses are dark and polarized, set in the frame in a semi-rimless design that looks streamlined.
