Just learned yesterday that Lowe's sells a Heated Jacket. It is Lithium-Ion, has 3 heat settings, 3 zones, 4 pockets, and includes a charger.
I also read one was used under a leather coat and the rider stayed warm in 25 degree temps.
I ordered one yesterday, it is being shipped to my home and expected on 2/28/2012.
A review will be coming...
