Julbo's innovative Aerospace Snow Tiger Photochromic Goggles deliver comfort and performance on both the skintrack and descent. Thanks to the ingenious Superflow system the lens can be 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 minimalist lens and spherical shape not only expand your peripheral vision but also reduce glare and distortion giving you a clear and true field of vision.
