Foggy dsl lenses

How do you prevent dsl lenses from fogging up. Cool cabin to warm humid air outside.

I personally use a Repti-Therm terrarium heater in a drawer with my cameras or in the camera bag when I'll be in the cabin for a while. They never get over about 80° which it safe for any equipment and more than enough to prevent condensation when you step out into the steaming he'll we all seem to cruise to. If you forget it, like I did last trip, you can warm up the camera and lens by turning it on and heating it up with the hair dryer on low held about a foot away. I always hold it so the air stream hits my hand just to be sure it doesn't get too hot.
