heat - Could a sleeping bag be warmer if you are naked inside?


I have heard conflicting theories about the best way to keep warm in a sleeping bag in the winter. Some people say you should bundle up in your sleeping bag and another theory says that you should be naked, because the warmth of your body will create a microenvironment of very warm air right next to your skin, since the sleeping bag and pad reflect heat very efficiently, and there is no way you will get that warm if clothes block contact with the air. Does this "naked" theory make any sense according to Physics?
