Sports glasses are primarily designed to fit snugly and protect your eyes, but they should also look good like these sweet shades by X-Loop for men. The frame is made of metal, and the arms are plastic, flexible and rigid in varying degrees and contoured to fit your head and face. The arms curve downward around the ear and feature the X-Loop logo on the side in silver and black. The lenses are semi-rimless with a dark finish that blocks harmful ultraviolet rays.
