Thick and sturdy, these nice wrap around sunglasses are designed by X-Loop and are sturdy enough for sports and outdoor activities. The frame is made of thick and solid plastic that still retains a lightweight feel that is comfortable to wear. The arms have a large rubberized piece at the ear for better grip and show off the X-Loop logo on the side. The lenses are small with a finish that protects your eyes from harmful ultraviolet rays.
