I have the Gerbing heated jacket and glove; both are the best. When riding in weather below 30 degrees for more than 1 hour my lap and the top of my thighs get quite cold (I ride a 05 1200RT). While my first choice is to add a layer under my riding pants I am considering the heated pants from Gerbring. However, I am concerned about them being too bulky. Does anyone have experience with the heated pants?
