It's always a good idea to pair your Julbo Excel Atlas Goggles with a bit of sunscreen, lest you end up sporting a gnarly goggle tan at the office on Monday morning. Raccoon eyes aside, the Excel Atlas Goggles serve up all the protection and high quality optics you need for a full day on the mountain. Their polarized lens and spherical optics reduce glare, enhance contrast, and ensure full peripheral vision as you ski. An anti fog coating helps to prevent fog from building up after back to back laps during those days when conditions are too good to quit. Working with the anti fog coating is Julbo's Air Flow ventilation system, which allows air to pass through, further reducing heat build up.
