My guilty pleasure and favorite ski toy these days are my ABOM goggles. These goggles have built in defroster sandwiched between two Carl Zeiss lenses. Bottom line is that they never ever fog up no matter what the conditions are like and because of the two lenses with no delicate anti-fog coating you can wipe the inside of your goggles without ruining them. For me this has been a game changer as I used to travel with multiple goggles and extra lenses to combat those extra wet and sticky days in the PNW where everything fogged over and moisture collected in between the double lenses. Definitely not the cheapest goggles on the market but worth every penny I paid for them. Lots of cool details on the tech and demos of the goggles on their website if you are interested in learning more. https://www.abom.com/
