I think UnderArmor is what you are talking about.

There are materials that "wick" mosture away from the body to help cool you. It can be worn under clothing, but I have really only seen it used during clod weather when you wear multiple layers. I usually just wear the essentials under my suit I still sweat :p But I guess that happens during any hot day.

UNDER ARMOR. Works great. I use it to play hockey under all my equiptment.
