Another vote for the pinlock visor. Just bought a Nolan N90 and it came with the insert. Has worked great so far, no fogging at all.

I considered this pin loc but I read that it distorts images. Whats your take on this?

this is going to sound crazy but I swear it works and lasts longer than any spray that I have come across. Cut a potato in half and rub the potato on the sheild, it will leave a film on the shield, allow the film to dry then buff with a microfiber towel. Poor man's anti fog and it works

Pin Lock, or a Fog City insert. I have the fog cities in all of mine!

Fog-Off.

I have used Fog City but if you get it wrong you're Fugged

What these solutions do is break the surface tension. yes spit will do it to but that might smell a bit! That's what i used to do when SCUBA diving.

I prefer to keep the windshield cracked ever so slightly.

Pinlock! They work and there is no distortion.
If you also wear glasses, your glasses will still fog up though?

+1 on that. I can't fog up my Scorpion even why I try.
