I just got back from four days of awesome skiing. Three at Winter Park and one at Steamboat Springs. Three days of temps in the low 40's and one cold cloudy snowy day. These goggle preformed great. NEVER fogged once. We skied over 90 miles according to ski trax. Hit it very hard in the warm weather and zero fogging. Last season my Anon Figments fogged constantly. Not these. I used the Red Solex mirror lens for the bright sun and the Gold Sensor Mirror for the cloudy, snowy day. Great vision.
