Rain, Mixed With Heavy Showers And Visor Misting
Blog Date - 08 October 2011
Sure has been wet today. The day started out with drizzle, with showers inbetween. By teatime when I started my 35 mile round trip to collect my son the drizzle was a low lying soggy wet mist, with showers thrown in. Today has been the first time this year that misting up on the inside of my visor has been a problem. I was passing over a high section of remote road and found that at some points my visibility in the fog and the rain and the mist on my visor was next to nothing, quite dangerous.
There's very little I can do. With the visor down even the merest mention of breath causes the visor to mist. I have tried holding my breath but find that after a minute or two I go all dizzy and faint, which is equally dangerous, so that's not an option. I can lift my visor up but then I get rain drops rammed into my eyes at whatever speed I am travelling, this causes me to slow down to a crawl or get blinded.
The third option is to leave the visor open by one click. This is a common solution for many bikers, but not without it's own issues. The logic is that the visor is low enough to protect the eyes from the pummeling rain, and the extra air flow around the partially open visor prevents misting. Sometimes it works just like it should, but often the wind blows into the eyes, causing them to stream and run-off rain from around the visor and the opening blows into the already wind-swept eyes.
There is no perfect solution. There is a sort of compromise. If you're in town and riding slow, leave the visor open if you can. When speeds pick up such that the rain is hurting then half-open the visor. When speeds increase to countryside pace then close the visor, the extra wind helps keep the mist at bay. Also make sure the visor is clean. I can't explain why by a recently cleaned visor seems to mist up less and repel the water more. There is one other tip. Slow down. There are times and weather conditions where even the cleanest visor and the most experienced rider just cannot see where they are going.

Hallo! I suggest to make selfmade breath deflector, from some thin plastic, to join the face betveen eyes and nose. It works great as alone, also, depends fron varios factors, wind, breathability of helmet and so on, and also this can be tuned further - adding somensoft foam bit, to make better contact with face, so not letting by the wet breath. Also, beneath the deflector, depends of helmets design, will be good ventilating place, you can get fresh air, and moist air gets away, or, if helmet is more hermetic, than I will add small flexible pipe from beneath deflector - to backside of helmet. All this is accomplishable without drilling holes or affecting helmets construction. By moving, wil be negwtive pressure at the pipe end, and this will suck out moist breath fron above the deflector. Good luck!
