So I was looking into new helmets, and I came across some promotional materials for Giro helmets. They mentioned some testing which said the majority of warm air from goggles escapes through the top of the goggle, and so they've placed two big vents on the front of the helmet to help minimize fogging.
I figured it was a bunch of marketing BS, until I looked at my own helmet. Similarly, the Smith Aspect has two vents, but the Silver smith logo makes the top left vent about half the size of the right:
What's strange, is that's exactly where my goggles always fog.
At really cold temps, my goggles have a tendency to fog on the top left of the lens, right underneath the smaller vent.
I find the Smith Aspect to be an awesome helmet overall - lightweight, stylish, and really comfortable. But could it be a culprit of my occassional fogging problem? And has anyone noticed fogging improvement when they switched helmets?
