Spit. On the inside and rub it around. That's if you have nothing else at
hand. Others will chime in soon with better suggestions but this works when
you have nothing else available.

Hehe, sure why not. After decades of skiing in fog / white out conditions
there comes a time when you can do it blindfolded.

Between the eyeglasses / goggles / faceshields / frosty windshield I've
learnd to make do safely.

Although I will never willingly ride into a snow storm on my F4i again.

+1. Wonderful things, Fog City Shields. Well, until they get a bunch
of little scratches in them. Gotta get a new one this spring.

In a bind, try breathing in thorough your nose and out through your mouth,
directing the exhaled stream down.

After trying both anti-fog coatings and Fog City, I'd have to agree
mostly with Ben. Fogging faceshields are really a problem only at
low speeds, low temperatures and high humidity. For those brief
occasions exhaling by blowing down out of the helmet works quite
decently. No stray reflections as from Fog City, no nuisance of the
coating having to be replaced (by the time you know it's necessary,
the spit routine is likely to be the only handy option).

It's useful to remember that if you're warmly dressed, a little cold
breeze through a (slightly) opened faceshield isn't all that bad. If
the cold really bothers your face, it might be time to warm up all
over.

Can even be an issue at high speeds if one is behind a fairing. If I
stand up, the vents in my helmet work well, and the fogging clears, but
when seated on the bike, the windshield directs the air in a bubble that
doesn't let the chin vent work.

Get the Shoei pinlock visor. Much more satisfactory than the Fog City
insert.

Ah, now my problem is making more sense. I have a windshield thingie, and I
know that the airstream touches only the top of my helmet. So, the chin
vent is relatively ineffective. Never thought about that.

One thing I've noticed is that commuting around town in cold weather I
tend to get fog on both the visor and my glasses. When I've been on
the road for an hour or so then it goes away and stays away until I
stop somewhere long enough for everything to warm up or cool down.
It's not entirely speed related--while I get less fog at 70 I still
get some for that first hour or so unless I leave the visor cracked
just a bit, then after an hour or so (might be a half hour, might be
15 minutes--I've never put a stopwatch on it) I can close the visor
completely and no problem. If I stop for lunch then I have the same
thing happen afterward.

I've been assuming that this has something to do with visor and
glasses coming to equilibrium temperature, but I wouldn't swear to
that being the cause.
