You can truly take it all in when you hike with the Revo Polarized Bearing Sunglasses. Their impact resistant Serilium lenses stand against pebbles and falls without a scratch while Revo's High Contrast Polarization filters out glare 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 added nose pads to keep the Bearing from slipping down your face when you work up a sweat.
