A fog-defying fan, glare-cutting mirror lens, and an angular frame combine to bring you Smith's Prodigy Turbo Fan Goggles. When you're booting up the hill, turn the lightweight, micro-electronic silent fan on high-power speed, and switch to low-power on your way down the slopes. The Prodigy Turbo Fan runs for up to 50 hours, so you can keep on carving as your buddies stop and fish around for their goggle-wiping cloth. Check the sizing chart to find the right goggle tint for you.
