breath fogging optics

Now that the cold weather has returned,
every time I breathe, my breath fogs up
the eyepiece. Anyone have a solution
for this?

Sure just don't breathe.. seriously, you can wrap your EP with a dew zapper cord, it attaches to the body of the EP via an elastic strap & velcro fastener, if the EP happens to fog over after you breathe on it, it will only fog momentarily, as the EP will be heated.. good luck, John M
