I have been trying the Icon helmet that was reviewed earlier on this blog and found that the shield tends to fog a little if you close it fully.
The fogging clears immediately if you crack it just above the locking dip.You can also of course use some anti-fog on the visor and will solve the issue right away I have also played around with the vents and none of them will completely clear the fogging that does occur.
The fogging mainly happens in rainy weather when humidity is already high in the lower temperatures.
