Everyone here is correct, lots of layers and wool. The only exception is cold windy days, it’s damn difficult to prepare for wind. On a -40 windy day there’s not a lot you can do. Hand warmers, or even better heated gloves can be amazing on those days for when you just can’t get your hands warm. My girlfriend uses a heated vest regularly and she loves it. I also almost always have a large thermos of hot soup or tea to sip on on break.
On stupid cold days I’ll sometimes where two wool baselayers. I find the layers rubbing generate heat and that can be lovely.
When I worked outdoors in the winter, I ended getting a higher-end breathable fishing gear. It created an external layer that stopped the wind. It took very few layers underneath to keep me warm. Often just a T-shirt and a light fleece was enough to keep me warm down to 0F. In colder temps a wool sweater and pants did the trick underneath.
I also combined it with neoprene skii mask and a wool beanie. For gloves I went with a thick wool knit over thinsulate when it was really cold.
