Rely on Uvex's Downhill 2000 Variomatic Goggle when you're charging powder from sunrise to sunset. Variomatic photochromic technology makes the lens adjust its tint from clear to dark according to your surroundings, giving you the right amount of shade whether you're skiing at night or midday. Supravision's anti fog coating works with the frame's climatic membrane to keep moisture buildup at bay. Uvex also added a frameless design with a decentered spheric technology to provide a wide, distortion free view of the terrain.
