Yea, it doesn't take much, is all I'm saying. Even as dry as it is here in CO, sometimes it is more humid than others, my goggles notice it first.
Some possible factors: goggles started out cold, goggles started out warm, your face was cold when you put them on, moisture from somewhere....hasn't happened since?
Environmental factor still seems to me to be the culprit, not the goggles.
You're probably right
