Raft down the Colorado with the Revo Windspeed Polarized Sunglasses enhancing the sights. Their scratch resistant Revo Crystal glass lenses enhance color, clarity, and contrast 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 blended copper, zinc, nickel, manganese, and iron in order to make the frame strong, corrosion resistant, and flexible. In fact, Motion Fit technology ensures this pair positions itself to ideal locations on your ears and nose, and the temple pads make sure these sleek shades don't end up swimming with the fishes. Revo also added adjustable nose pads to ensure a solid fit.
