So after some different field testing, I found the perfect way to keep my iPod going in even -22F weather.

iPod in a SmartWool sock.

It kept it going pretty well and didn't require any special heating. I still might make something similar just to see if it works (Thanks TonimusMaximus for the link), but at this point the easier the better.

I don't really want to keep my iPod wrapped in a sock most of the time. Basically I am going to chop apart a fairly well used SmartWool that is missing the mate, wash it well, use it for the main material, and sew a cover around it.

I have an idea of how it will look already. It's a shame that pearl button clasps are hard to find in sewing stores. Don't bother sending me a link - It's just something that I'd rather pickup in person.
