Hmm that’s no good! We haven't heard it from any of our sponsored athletes, but after reaching out to our Olympian, she said is that the only time she has had fogging issues is when there is something covering her mouth. Basically when this happens their breath goes back up through their vents at the bottom.
That being said, if you wiped off your lens in the inside, you may have removed the anti-fog coating in there.
