This is what riders have been doing since motorcycles were invented. Thin layers that create a bubble of air around your body so it stays warm but can also breathe. The notion "cold will eventually win" isn't true. Natives in Alaska don't wear electrically heated clothing and the cold doesn't "eventually win". It's knowing what to wear and how to wear it.Silk base layer, socks and glove liners, works wonders!
With that said, I love heated gear. I've done both but when it's in the 20's and 30's the thin and easy to move around in heated gear is the way to go. However, if you're on a long ride you will want to carry layered clothing just in case the electric heated gear fails. There's nothing like being 50+ miles from civilization in 20 degree weather and having a wardrobe malfunction.
