RDAY, I don't hear problems with fogging up with the mod 2 hardly at all. I know a lot of people who have that helmet (the wife and I as well). Are you using the fighter pilot mask that came with it? 2nd...are you using the filters in the mask? 3rd...if you are using the filters...are you replacing old wet filters with new dry ones? The actual filter or something has to be in the fighter pilot mask. I don't use filters anymore...instead what I do is I take a paper towel and roll it up. Stick the rolled up paper towel and put it in the bottom of the mask...just cut down/tear the paper towel so it isn't too long and covers up your air vents. Make sure the mask fits snug on your face. Make sure the mask has a seal around your nose and there isn't a gap. A balaclava is also good to wear over your nose/mouth area. Buy some anti-fog spray and cloth and put it on the shield...I treat the shield at the beginning of each season. I always keep the chin vent open and the vent on the back of the helmet open also. Also, if it is really cold out and you are experiencing some fogging or to prevent any fogging...at each stop or road crossing...just pop open your shield to let some air in. Once you are moving for a bit close it up/seal it again. I have been using this mod 2 for 5+ yrs now and never have I had it fog up on me...but I do about everything I stated above.
