Unfortunately doesn’t work for me. I have (self diagnosed) what is called raynaud syndrome where my body sends a signal to immediately draw the blood out of the hands when it’s very cold. They literally turn white. I need to cycle really hard and stop for a couple of minutes so that there is less cold airflow to get them back and usually they get cold again over longer rides. This is only a problem at below say 5-6 degrees but it’s very annoying.

You should specify which Winter you're experiencing. I'm assuming you aren't in sub zero temperature

I wear gloves for the first 3 minutes of cycling. After that heating has booted up, circulation has made a first full cycle and unless its very windy and snowy, I take my gloves of and my hands stay warm for the rest of the ride. Nice feeling actually.
