Look great while knowing your eyes are secure and protected behind the Wiley X WX Tobi Sunglasses. The frames are made of heavy-duty nylon that is extremely durable, but also light and comfortable enough for easy all day wear. The polycarbonate lenses are shatterproof and block 100% of harmful UV rays, so you stay protected from every angle. Secure, non-slip rubberized temples help hold the sunglasses in place, allowing you to engage in many activities in different environments without the fear of losing them. Both the frames and lenses meet ANSI Z87.1 High Impact and Optical Performance standards, and the Tobi Sunglasses are rated as OSHA grade occupational protective eyewear. On top of all these performance qualities, these sunglasses also look stylish, making them perfect for any number of occasions.
