Two things... 1) Rain mode (if you've got it) on the bike, that helps tone down the throttle response curve; and 2) If you don't have a pin-lock face shield, use Rain-X for plastics on both the inside as well as the outside - helps prevent fogging

I've got two rain suits... a one-piece and a two-piece... one-piece has a hood that goes inside your helmet... if I know for sure I'll be in rain, I use the one piece...

Make sure you use the "Interior Glass Anti-fog Rain-X" type. This type has hydrophilic property (attract to water) and spreads the water to the surface, preventing droplets. Here is the link to the product: Interior Glass Anti-Fog - Rain-X

There are videos in YouTube which use different materials to apply to the inside of the visor like toothpaste, or baby shampoo to prevent fogging. I do not like using toothpaste as toothpaste has abrasive material. I tried baby shampoo but had to give up because it gave me haze and halos at night. YMMV.

Good point and correct!

And I've tried the baby shampoo as well before - didn't work. That's why I went to the INTERIOR Glass Rain-X... https://www.amazon.com/Rain-X-630046-Interior-Glass-Anti-Fog/dp/B00T9LR9FA/

Dang - I didn't even think of using this stuff on my glasses - what a great idea!
