X-Loop knows style and knows how to make a good looking pair of sports shades, and these sunglasses for men are proof of that. The frame is made of strong plastic that looks thick and tough, but still sits lightly on your head for long-term comfort. The arms are thick with a taper at the curve of the ear. The X-Loop logo is seen on the arms with a cool red accent on the X. The lenses are dark rectangles. Purchase these great shades in bulk for additional savings.
