Advance Sunglass - Zebra Anti-fog Lens

After testing the Advance Sunglasses in mountain ranges all over the planet, Julbo made them even more versatile by adding Zebra Anti-fog Photochromic Lenses. These lenses adapt to external lighting conditions and provide visible light reduction from 60 to 93 as you go from valley to treeline to glacier to ridge to summit. Use the Advance Sunglasses for the forested approach, and then snap on Julbos removable rubber side shields when you get to the snow-covered world.
