Lightweight and sturdy at the same time, these sport sunglasses are made by X-Loop specifically for men who enjoy being outside and participating in sports and other activities. The frame is made of metal, and the arms are plastic and will bend enough to be comfortable while remaining rigid enough to hold their shape. The arms are thin and rounded with a cool design on the side. The lenses are set in a semi-rimless style and have a smoke finish to protect your eyes from the sun.
