Don the Revo Polarized Heading Sunglasses whether you heading is a snowy peak or a sandy shore. Their impact resistant Serilium lenses stand against pebbles and falls without a scratch while Revo's High Contrast Polarization filters out any glares to leave you with natural, clear, and comfortable eyesight. The Element Shed and anti reflective coatings keep water, dirt, oil, and nasty reflections off these high performance lenses. Revo made its proprietary Eco Use frame partially out of castor beans in order to make it more flexible without harming the environment, and Motion Fit technology ensures this pair positions itself to ideal locations on your ears and nose. Revo also added nose pads to keep this sleek pair of sunglasses from slipping off your face.
