View submission: How did people stay warm outside?
Ranulph Fiennes clarified this in his Shackleton book: reindeer skins and furs only make sense when you run dog teams like Amundsen, because of wind chill.
When you manhaul like Scott and his team you sweat more and get very warm, which makes canvas and wool layers a much better choice.
In answer to OP depends on the period but generally layers of wool and fur are very effective at keeping people warm in northern latitudes.
That and fire.
There's nothing here!
