Julbo's innovative Aerospace Goggle with a Snow Tiger Photochromic lens is the first goggle designed to be worn on both the skintrack and descent. Julbo's new Superflow system allows the lens to pulled away from the frame, reducing heat buildup and fogging as you climb, and can then be pressed back into the frame to reduce airflow once you're ready to ski. This innovative technology means these goggles can be worn on both the up and down, so you won't have to be constantly switching between sunglasses and goggles during transitions. In addition to the Superflow ventilation system, the goggles also feature Julbo's high end lens technologies. Snow Tiger photochromic lenses will adapt to changing light conditions as the day progresses, while the spherical shape not only expands peripheral vision, but reduces glare and distortion, giving you a clear and true field of vision.
