Large Water bottle or one of those heated pads that you can add warm liquids to. I do this camping when I'm sleeping in cold environments. Fill the container with as hot of water as you can stand on bare skin without pain. One between the legs and one near my chest does the trick for a couple of hours. Refill when needed.
