I know, most of you will think this is a stupid question, but:
Can Under Armour Heat Gear help keep you warm in the cold? I know it says for use in "extremely hot weather", but I don't know all the science behind it...does the design help keep your body at a moderate temperature (keeps you warm if it's cold and keep you cool if it's hot) so it can really go either way and the "Heat Gear" name is just a marketing gimmick? Or is there a real difference?
I'm wondering because I found a really good deal on their Heat Gear but what I'm really looking for is something to keep me warm in cold weather.
