I'll have to disagree. It depends on how much you sweat. I'm okay as long as I'm moving but when I stop my glasses fog immediately. I usually pull them a little away from my face to keep it down to a minimum but that doesn't stop it. When I start rolling, they clear very quickly.
The one time I tried a face mask, I fogged up and stayed that way. If I use a balaclava, I have to keep my nose and mouth clear or I can't see nothin'!
Wrap around glasses that fit close to the face are the worst, subligar. Get some that stand off from your face a little and allow for some air flow.
