That's the way to go. I also have the Keiss heated jacket, with arms. It has a five way controller and is just lurvely!.
With the heated grips, Tucano muffs and my heated jacket I can be comfortable no-matter what the weather throws at me, especially as I have totally waterproof Klim jacket and pants and the best Sidi Adventure boots which are also waterproof. Bring on the winter camping!
