I agree with the "use you Mog" approach, though not when it is icey and there is a lot of salt, mostly becuase washing the salt off with cold water isn't fun!
I've got an electrically heated waistcoat, a legacy from bike days, and with the heater on full it is warm and rather nice. A bit like riding a bike without the risks and discomfort!
... and without the thrills.
