Foggy glasses in cold weather-lets fix it
I went out snowmobiling today and I found that my glasses kept fogging up. The face shield of my helmet was also fogging up. I ended up riding in -22 degrees at 50mph with no glasses and my helmet visor up. Somehow I made it through the day without getting killed or getting frostbite. I have the same problems with my glasses when I ride any form of open air vehicle or bike.
Lets find a solution once and for all. I'd like to collect as many suggestions for products as I can here. I'll try each one and I'll post the results. I've already heard a few. I can't remember the screen names these came from. I'm sorry I didn't give credit where credit is due.
Moving air over the glasses:
Today I put all my riding gear on in a warm tempurature and then I made sure to keep moving outside while leaving my visor one click open. The wind kept my glasses and visor clear as long as I was moving. The visor was closed enough that my face stayed warm also. As soon as I stopped however they started slowly fogging again. This does work extremely well but is difficult to maintain in some situations (such as snomobiling).
I'll try this out this week since it'll be below 0 all week. I'll let you all know how it goes.
Take care and I can't wait to hear more suggestions
