I used to regularly ride my bike to work at -40C. Once you’ve had a few weeks of that, you only need a little jacket at -20c. Yukon, Canada. It’s all relative. The coldest I ever went walking in was -48c just below the arctic circle in November, not counting wind chill. I’ve also hung out in +48C a couple of times. Still hoping I can get a hundred degree temperature swing.
