Agreeing and echoing with the above comments.

I have a heavily insulated Mountain Hardwear winter jacket that is close to 20 years old, but looks like new as I’ll only use it to bicycle commute to work when the temperature is below 10°F— it is just too damn warm for any kind of exertion.

From a lifetime of camping and skiing, the answer absolutely exists in layering. Even on cold-ass winter days, I am super cozy wearing
moisture-wicking t-shirt
Merino wool base layer (Smartwool have been my go-to)
Arc’teryx lightweight hoodie
Either a Helly Hansen or Mountain Hardwear outer shell (non-insulated).

If I get too warm while shoveling, biking or skiing I can peel a layer before I start sweating, and add it back if the chill creeps in. A single super insulated coat doesn’t give you any flexibility to regulate your temperature.

Also, same goes for the bottoms; usually it’s underwear, wool long underwear, and outer pants— never an insulated pair of pants straight-up.
