These semi-rimless sports sunglasses for men by X-Loop are unique because most glasses of this style have a metal frame, but these cool shades are all plastic. The lenses are rectangular and are mirrored for maximum privacy and protection from the sun. The matte frame is thick and solid looking, and the arms continue this structure as they taper toward the ear. The arms feature the X-Loop logo on the side and a cool design element as well. The sunglasses come with several lens and frame color options in the dozen.
