I am going to afgan as I have told many of you. I would like to see if I could get some help. Its really cold oever there and not much can be done, but i once saw this suit you can wear and its a body suit heater. I really want to get one, but not having much luck finding it one. Could yuou guys help if you know about one, the one I saw is not bulky and very slim and trim lined with your body. Also what else do you think I should take extra, I am gonna take a GPS and a some other gadets, any tips from vets?
