I figured I would ask this here as it's probably something that riders are more familiar with and simply due to the sheer number of riders on this site versus track rats such as myself.
My Arai GP-5W auto racing helmet often has problems with the visor fogging. I think part of the reason is that the 5W has a larger eyeport (literally, W for "wide"). My race supply shop, and even Arai, have said to simply crack it a bit to bring in a bit more ambient air. While this does works, I have a few reservations about doing it from a safety perspective. It's also a bit distracting since I have a mirrored (dark tinted) visor and cracking it lets in light. This has bugged me since day one with the helmet and I was pretty close to buying a different one with a smaller visor in the hopes it would not come into contact with my breath, such as the GP-6S.
Arai does make a dual-pane/anti-fog visor but it's pricey and only available as clear, yellow, or "light tint". I believe you motorcycle folks call this a pinlock. I found some "universal" anti-fog inserts that supposedly work on any helmet but I wanted to ask if these really work. I know there are also those sprays and gels, but I talked to two Arai tech support guys and they said not to bother.
