Outdoor enthusiasts know how valuable a good pair of tough shades can be, and that goes for outdoor sports as well as camping and anything else under the sun. The frame on these cool shades for men by X-Loop is made of plastic, designed to be strong with a shape that fits your head comfortably. The arms start thick, then taper to a curve at the ears and feature a stripe section and the X-Loop logo on the side. The lenses are rounded rectangles with a finish that blocks the sun.
