@Allan Oleson Yeah, I have tried various of the wools and they cannot be the layer directly on my skin. I have some alpaca and merino that works fine if there is something between me and it. But for under dry wear I have to be synthetic (silk turns into a soggy mess very quickly). It works out fine, I use something like CoolMax or poly for the base layer and mostly good fleece for any second layers needed, and I find that combo works well to keep me warm while wicking well. I get damp but not soggy.
It is a shame because wool is the only material I know of that can be wet and still function to keep you warm. That detail kept me from going into later stages of hypothermia once in my younger and more stupid days.
