Large and very warm winter coats are Woolrich’s bread and butter.
This particular large and very warm winter coat is called the Pocono Parka. Its insides are stuffed with a mixture of down feathers and actual feathers (eighty percent the former and twenty percent the latter), so the whole experience is a bit like walking around in a sleeved and open-bottomed sleeping bag. The detachable fur collar-lining looks nice and soft, too, and I suppose there’s nothing stopping you from removing it and stroking it, even in public.
So maybe you should buy one ASAP, from Oi Polloi.
