I'm trying to find a good helmet and/or visor that reduces fogging. I've done the penny thing taped at the bottom of the visor (it lets in debris which pits my glasses), the breath deflector, and anti-fog liquids. It's still awful in dry - never mind the rain.
Are there double visors around like on ski goggles? How about a helmet that moves a LOT more air? My old M3 does not seem to cut it.
TIA
