Do you have the breath box seated properly on the BVS helmet and have you made sure the electric shield is working properly just thinking if you use the same cable on both helmets maybe a cable problem
ive found that fogging up actually has more to do sometimes with your body over heating? do you sweat when you ride? if your over dressed and getting a bit warm, ill fog right up
Very important. I discovered with mine that in trying to get a good seal, I was actually tightening it too much and distorting the intake valve. As a result, my exhaled breath was also escaping out of the intake valves and into the helmet.
Definitely. And if you have to do any type of exertion that may cause you to sweat (getting unstuck, unloading, etc.), consider taking the helmet off and quite possibly your coat too. Sweating is not the BV2S's friend.
My fogging problem in the BV2S (including my glasses) went away when I stopped wearing a balaclava and went with just a neckie
I've had the Doo EXO Scorpian and BVS2 helmets both with electric visors and fog up more thn 50% of the time. Looking for a helmet that will not fog up. Does such a helmet exist?
Yep. I've found the BV2S to be so warm I rarely need a balaclava. Only when it's REALLY cold (like single digits or below) do I consider wearing one and even then it's not a thick one.
