Ive had these goggles for 3 years now and have never had a problem with them fogging.....until recently. I experienced all 3 lenses I own all fog up between the two lenses where its sealed. I was hoping someone out there had any insight into this problem. The outside temp was around 15 degrees and I wear a Bern hard hat helmet, might these have something to do with the fogging issues?

after I drop a lens in the snow or heavy use I've been drying them out like you would electronics in a sealed container with dry rice inside. this same thing happened to me with these and some Oakley Aframs.

Yule & Bellow answered it perfectly. Make sure after you ski you let the goggles sit in a warm place for a couple hours, then place them back in a dry case or bag and they will be ready to adjust to the conditions again. If you keep them moist or cold from skiing and then go out again the next day they will fog. This Happens to me every time. I always make sure they have time to warm up and dry in a warm room for at least a couple hours.

If the fog isn't going away you are going to have to dry out the inside cause there is a good chance its because of moisture trapped in between the two lenses

I had that happen to me with both these and my EG2's, it happened when I wrapped them up in the bag without letting them properly dry out after boarding...all the moisture built up between the lenses and took a good few hours of room-temp venting to fix The other thing I've had happen was that fog built up on the inside of the lens, like normal...but it was really cold and I popped them up into my forehead to see, the fog on the inside of the lens turned to ice and then the ice fogged the space between the lenses...did you expose the inside of the lens to the cold air?
