"I don't follow? How is a thin hood going to compete with a windproof balaclava , face mask, hat, neck gaiter, and goggles?"
If you have a hood, you might be able to do without, say, the neck gaiter and either the balaclava or hat, your choice. A few less bits and pieces to fiddle with.
"Not to mention that I would want something more than a wind shirt for subfreezing windy temps-which we get a LOT of around here: like a wp/b shell."
Fair enough if things get bad enough, but the same logic applies, i.e. WPB shell with a hood. My 2 cents.
