OregonMouse, that's a great tip about the Capilene 2. I'll check out my local stores to see what they have. Not much hope, but at least if I can find something to try on to kinda feel out the fabric. I was also thinking of trying some smartwool over top the Capilene 2, just to check out how it felt...might get away with such layering up that way.

Thanks to all for the interesting observations in this thread.
