Yeah Doc, yer right. If I lift my hat, the fog clears right up, but ya can't do that when your shooting. And I tend to get hot during the stage, not when I can do something about it. So looking for a little help.
I learned the same when I was a wild man ski-devil. I have a one piece over-suit for skiing.. We'd fly down the mountain, cooking and smoking and then I'd unzip the top, only a T-shirt underneath and steam like an old train. Cool off in line, then zip up for the lift up and down again.
Gracias,
