In my short experience (2 SCCA schools this fall) I have had problems with my faceshield and glasses fogging up when I closed the shield on entering the track for the first session of the day. Very disconcerting!
There seems to be a variety of anti-fogging products on the market: anti-fog sprays for glasses and faceshield, anti-fog overlays for the inside of the faceshield, and a breath deflector.
Have other listers had any experience - good or bad - with any of these?
Thanks,
John
