Lightweight and comfortable to wear, with an inward curve that keeps them on your head, these great shades are made by X-Loop for men and are intended to be used in sporting events and outdoor activities. The frame is made of strong and durable plastic that will hold up to rough treatment. The arms come off the top of the face and flow back to the ears where there is an interior texture section that adds grip. The lenses are dark and set in a semi-rimless fashion.
