Warm winter jackets.

@61scout - which modle is it? I would love a Canada goose as I'm not doing activities in the cold more standing around doing nothing.

Living in the land of cold, 6 below F right now, we like to think we know how to dress warm.
I always start out with the important question what is your budget?

There should be lots of sales going on right now.

Layers are very important.
For best bang for your buck a layered Columbia type waterproof/windproof parka with hood is your best bet. Get one that has a removable liner of some type.

So overall some type of insulated shell that has room for you to add layers underneath, heavy wool sweater etc.
Keeping the wind out is a huge factor.

Wool Jackets such as Filson are great also but unless you are active keeping yourself warm the wind will be going through it cooling you off.

There are people that will have a wool jacket underneath and wear some type of wind stopping anorak over the top.

Layers are important as are jackets meant for cold! Some guys think that a heavy FQHH or Steer hide jacket will be warm because it's heavy and well, warm in the warmer temps. Not at all, unless it's a shearling B3/B6/D1 or the like.

Mine at the moment is a Pike Bros N-1 "Deck" jacket. It's super nice for the cold. I also have a similar RRL jacket that is likewise warm. On the cheap end, I've got some Carhartt items that have the "sherpa" lining. Great, and warm and cheap.
I'm contemplating getting a Patagonia "down sweater" for carrying around on day hikes, etc.

I've got a closet filled with stuff that I choose from daily, and even here in Pasadena, we get into the 20ºs and 30º every year. I also travel, so I can't just have warm weather gear.

Forgot to ask why you sold your bomber? I'd love a nice black B3 Irvin type with black shearling.

I picked up this Carhartt jacket at a farm supply store in central Illinois when I was up there doing some work last winter. It's called the Jefferson traditional jacket, and I got the "canyon brown" color, FWIW.

It probably won't win you any fashion awards, but it will keep you warm and dry. And I think Carhartt has a few jackets made from similar materials (their Quick Duck poly/canvas blend outer layer with Thinsulate lining) in a more casual, rather than workwear oriented, design. Anyway, I like that my Jefferson has pretty beefy insulation and a moisture and wind resistant shell but still allows reasonably good freedom of movement. That's key for me since I had to do a bit of work in it (logging boreholes, developing and sampling wells, etc.) but likely wouldn't be as important to someone looking for maximum warmth who doesn't mind sacrificing a bit of mobility.

The interior storm cuffs on the sleeves are absolutely a must-have for me as well. There are few things worse than snow and ice getting in your sleeve while you're working. First off, it's cold. Then your body heat melts it. Then it's wet. Then because you're wet, you're even colder than before. No good. Again, this is a work-specific feature I gotta have. If I was just wearing the jacket to commute to the office or something, I'd have a less sanguine view of the storm cuffs because they make it a bit of a pain in the ass to locate your wristwatch (leave it up inside the sleeve where it's uncomfortable and you can't see it, or push it through to the outside where the crown will be catching on the cuff and causing the sleeve to bunch up in annoying ways all the time?). If your top priority is keeping bad weather outside where it belongs, though, storm cuffs all the way.

The only significant drawback with this jacket in terms of its foul weather performance is the lack of a hood. Personally, I don't mind this much because I prefer to layer a hooded garment underneath my outer layer anyway. Integrated hoods tend to be too big and awkward for my tastes, and the ones that roll up into the collar make the collar much bulkier than I like. Some folks I've worked with feel differently and like having a built-in or snap-on or roll-away hood integrated right into the jacket so it has that option as a stand-alone garment. They're not wrong, I just prefer a different setup.

To finish up, I gave this jacket a solid field trial while wearing it for the better part of two weeks of working outdoors in 5-20F temps for 8-10 hours a day. When I had it layered up with my Patagonia micropuff pullover and a nice thick hoodie that Wifebert brought me back from Palmer Station on top, my Carhartt insulated bib overalls on the bottom, and an assortment of thermals and your other standard layering pieces, it was damn cozy. I was usually quite comfortable, and when I was cold I wasn't bone-chilling cold. And let's face it, when you're out in 5-10F for several hours and there's some wind, you're going to be a little cold no matter what unless you're fully kitted out in some high grade mountaineering gear and you look like you're on your way to a Mt Everest summit attempt instead of a desk job.

If you're looking for ultimate warmth I'd recommend either Arctic series from Canada Goose or Rock and Ice Parka from feathered friends.

Personally, I'm never static outside, so I rely on my body to generate some heat and I layer up. A thick fleece and a decent merino wool (icebreaker) coat on top does the trick for me up to -20C (-4F). Anything below, I use a down jacket.
