I’ve done some rides below 0F in still dry air, just wearing a short sleeve cycling Jersey - and still end up sweating (riding up a ski hill). Then if the wind does pick up even a little, you can get cold quickly.
I also use vapor barrier liners on my feet - and they get a bit nasty if you sweat too much inside them!
Short rides are more forgiving on temperature control - meaning if you get it wrong and sweat too much, it’s not too bad. But not good if out for 4 or 5 hours.
I headed out this evening for a short ride in 2-3” of fresh snow. It’s very quiet and peaceful in conditions like this.
