Yeh, I've heard that old story before. It surely
didn't work for me when we used to go backpacking in the Sierras at 12,000 ft.
elevation. I wore ski pajamas. Much warmer.
Also, if any of you women marry old boy scouts.....don't believe them
when they say you will sleep warmer in sleeping bags if you sleep without
clothes. Boy was I naive....and cold...
