    I was wondering just what the longest span in hours you have experienced with the disposable heat packs (tear off wrapper, shake and put in shoe, glove, etc). I opened one yesterday at 6:15 a.m. for deer hunting, put it in my pocket and hunted til afternoon. I stuck it in my coat pocket for the trip home and this morning when my wife and I went out to go shopping it was still putting out heat. It is now 12:30 p.m. and it is still warm for almost 31 hours continuous output. Brand is Heat Factory and it is a pretty big one...maybe six inches square. Your experiences?

    it somewhat depends on where you have it. the more fresh air the faster it will burn up. you can keep a zip lock bag with you and they will last a week.
