I recently found some USB powered heating back belts on amazon for $25. I keep a battery bank in my pocket anyways to keep my phone charged, so it would be easy to wear that under my base layers and pipe the cord to my pocket. Cheap back support that heats my core and doesn't add bulk might be a winning recipe if I ever move out of the south.
