How can I prevent my binoculars from steaming up?
I went for a walk last night in my local woods. I took a pair of binoculars with me. It was quite a cool evening (not that cold). Every time I put the binoculars to my face though to look at something they started to steam up! When I removed them they'd clear only to fog up again after a few seconds of looking though them.
I had the binoculars slung around my neck for convenience. Is there anything I can do to mitigate this problem?

I tend to tuck mine inside my outer layer of clothing if it's cold but dry. This keeps the lenses warm so avoids condensation. It helps with camera battery life too.

You can buy any of a number of anti fog gels and materials that are made for scuba gear, but also work great for binoculars.
That said, we always just solved this problem by spitting on the lenses and wiping. It's gross, but it worked.
