New trail-tested advice for shading your face from the sun.

You know the importance of shading your face and ears from the sun's harmful ultraviolet (UV) rays, since sunburn heightens your risk of skin cancer. But did you know that a hat with a wrinkled, uneven brim wards off UV light more effectively than does a hat with a rigid, straight brim? The wrinkles provide more reflective surface than a straight brim does.
