Replying to Ideas for ipod insulation

ok so im sure this is a problem for other people, but every time I take my ipod to the mountain (or any places cold) it freezes and stops working until I put it under the hand dryer or something warm.

I have a really warm jacket as is but ive tried putting it in some socks and a wraping it up in some other small cloth things but those just arent really insulating enough and it still freezes. My ipod has frozen and reheated so many times the the screen has some blank black spots in it.



short version then: ideas for keeping my ipod from freezing on the mountain...its on the brink of breaking.
