Layers are overrated...quality base layer is everything

[Alan]

Everyone says dress in layers. Sure, fine. But if your base layer sucks, nothing else matters. I spent money on good merino wool base layers and it changed cold weather hunting completely. Stop cheaping out on the foundation. What cold weather gear investment actually made the biggest difference for you?

First, great quality underwear.
I dress in thin layers right now. I have long sleeves on, and sweats, and socks. I like a good hat, but not required.
