I wear wool every day during winter. Thin, woven wool inside regular work clothes and thick, knitted wool as 2nd layer. You can machine wash wool on 30 C with wool detergent, air dry lying flat. Be even more careful with home knitted wool, I only hand wash. I basically never wash my wool. Only the thin, woven ones because it gets sweaty since I wear it every day directly on my skin. But only like once a month. I have more pairs of trousers and jumpers that I rotate between and air out. Socks on the other hand is washed after use on wool program. They don’t last so long, but stinky, pretty cheap, woven wool socks can be replaced. My home knitted, thick ones used outside of another pair on the other hand…

I’ve got the Nuuk one. A friend of mine bought one used many many years ago, and I just got one a couple years ago when I moved to a place that dips below -25 C during winter months. It’s amazingly warm, the warmest I’ve ever owned, and I love that it’s so durable. I don’t think I’ll have to buy a new parka ever again unless I outgrow it
