I have owned these googles for 3 seasons and they have been amazing. I don't have any fogging issues with the goggles, the lenses are durable and difficult to scratch, plus vision is greatly enhanced in snowy and sunny conditions. Fit very comfortably over eye glasses and great seal around the face with very durable and soft materials against the skin. Chassis, lens and strap made with high quality materials and look amazing! Optics are second to none. Price is higher than most, but then I guess you get what you pay for.
An issue I have had with these (not necessarily related to the goggle design): Although they fit extremely well over eye glassess, eye glasses (not goggle lense) can fog up. I have never had fogging issues with the google lense itself. I suspect there is not enough airflow to accomodate keeping eye glassess free from fog in certain conditions...most of the time it is not an issue.
Also in foggy or freezing rain conditions, I had ice build up on the outside of the google lens, bu that would happen with any non-heated goggle.
