I wonder what you have to wear under a coat like that to be comfy in -54, I was in Wyoming a dozen years ago -40 with 25mph breeze. < Crazy cold to me, I think a coat would have to be a foot thick to keep a person ?warm?
Not really. My 'Eskimo Parka" made for me when I was in Pt Hope by a seamstress there in mid 70's is made of mouton sheep skin, wool in skin out. The skin stops the wind, the inch thick wool keeps the warm in. There is enough airflow from the thigh length bottom through the neck opening to keep the moisture down even with moderate activity.
It is heavy, but saved my ass at least twice. Can't wear it much above -20 tho, unless sitting still. O or colder and snowmachining works.
Generally I just wore long johns and street clothes under it, with heavy bib or hip snow pants for bottom.
