Say these at a supplier of mine and they look like a viable solution for those with not a lot of surplus stator power. A friend of mine has one and he raves about it. lasts 3 hours on the medium setting and 2 on the high setting. Could be a great first layer with a good coat over top and bring a few batteries with you. The 12v batteries are readily available at your favorite home center.
I gave one of those to my wife last Christmas and she loves it. Only problem I can see with using it on the bike is carrying the spare batteries and the off chance you land on the battery in a crash- the battery pocket is right over your left kidney.
