A felt military cloak, perhaps from WWI or II. Like a long coat w/o sleeves, had a big hood. Has buttonable slits that you can poke your hands out of if you need to unlock a door or something.
I'm not joking. I used to own one of these and it was INSANELY warm, even in Minneapolis in the dead of winter when it's too cold to snow for weeks on end.
Lots of freedom of movement. No tight clinging sleeves, etc. They usually have shoulder straps so they it be unbuttoned and then thrown over one or both shoulders. In a car, it's like having a thick blanket to wrap around yourself.
The cloak, when buttoned up, acts as a chimney: funneling warmth generated by your legs (from walking, etc) up to your torso and arms.
Sure does look funny, but honestly after wearing one of these for a few seasons, I have no idea why they went out of style. A longcoat made of the same material offers only about 25% of the warmth that a cloak does.
