Here is a heated suit that I doubt you will get cold in. You will need NO other outer garments.

You may or may not want to try it.



Now as to what it will do to scare deer off or burn the woods down is a whole nuther story.






But seriously, when I want some extra protection against the cold I just use strips of good old duct tape and secure some of these to my first layer. 1 near the heart and 1 on each leg near the artery usually does wonders. If your feet get cold easily a few on your inner calf will do it. (I can unzip the legs of my bibs and jacket if I get too warm.)



Alot cheaper than an electric suit.

Even with a heated motorcycle/snowmobile suit you are going to have to figure out a good source of 12VDC like a real good motorcycle/snowmobile battery. And it will go dead everyday.
