:: It starts with pigtails. They cover if you haven't bathed in a few days (ahem), and they keep your hair out of the way while still keeping your neck warm. On really cold days, I forego pigtails and just let the hair hang, caring little for how dirty my hair started out or will get.
:: Next, the first layer of long underwear. I'm a HUGE fan of Smartwool, but my pocketbook not so much, so I don't get this pleasure every day.
:: Then, some long, warm socks, over the long underwear for comfort and to keep out drafts.
:: Next the second long underwear shirt, usually with a zip collar, just to vent a little if it gets warm (like in the 40s!).
:: Next comes the crazy yak wool double knit sweater and rib knit sweater pants I purchased in Xining, China many years ago. Xining is on the edge of the Tibetan plateau at 7,400 ft, a launching point for further adventures at 11,000 and 12,000 ft, so they seemed an especially practical purchase at the time. There have been many times since that I wondered whether I'd ever need them again outside of Qinghai province, but these things are the bomb!!!
:: Over all that goes the Carhartt insulated bib overalls. The only thing these are missing is a hammer loop.
:: Then, before I head out the door I pop on a hat, my Baffin insulated boots (they fit under the bibs), insulated gloves, and, if it's really cold, my D.I. down jacket and a scarf.
Here's what the ensemble looks like:
