I took my fat bike out on Monday w/heat packs in my gloves. Next morning I pulled the packs out of my gloves and threw them in my pocket to discard when I got to work. When I pulled them out to dispose they had re-heated to warmer than when I was biking the previous day.

I will try the ziplock bag thing next time if I remember.
