I've got a satisfied smile because I was camped well north of the Arctic Circle, up in the Alaska National Wildlife Refuge for nine days last years. It was actually sunny, but not particularly warm when I took the selfie. Before the trip I took the plunge and bought my first down jacket in over 30 years... This is the "Super Down Ultra Jacket" by Kuiu.
It's very light, only about 6 ounces total! Crushes into a small enough bundle to fit inside a pocket on my backpack. It's made to be worn like a thick, insulating shirt or sweater. Over the base layer, and under the shell garment.
Amazingly, they high-loft goose down has been treated so that water does not affect the insulating abilities! That was the downfall, pardon the pun, of older down garments. It's not an inexpensive jacket, but it's so light, comfortable and warm, that perhaps it should be considered by those who venture into cold climes.

I have Tru Spec pants...good stuff
After finding out that my supposedly waterproof jacket was not, I picked up a Tru-Spec parka and polar fleece through Amazon. It was quite comfortable in the cold last fall camping in Douglas Creek, and has now withstood an entire soccer season of standing in the rain during practices and games, all dry and warm. The price at the time was great, and they are still reasonable on Amazon, certainly more than my Columbia Interchange.
It's not a lightweight hiking jacket though, certainly not one that compacts to anything tiny.
The only downside to the superlightweight jackets is durability. Especially around camp. An errant spark makes quick work of the thin shell. I have an Arc'Teryx jacket that sounds similar to yours...it's full of holes :(
