You'd be surprised how very efficient a horse's coat is as an insulator. I know that some breeds do not grow good winter coats and may very well need a blanket. But most don't. We had a lot of snow a couple of years ago and the horses literally had snow on their butts. It didn't melt because the fur is such a good insulator. Keeps heat in. But , it's critical that they have lots of hay to be able to keep their "engine" roaring.
