Like Roarmeister I have also had a few synthetics that got pinholes on them from blown embers. And you don't have to get defensive teslin, I don't have anything against synthetics at all. I own and use synthetics that I wear and really like.

I just like wool as well. Smartwool is very nice. I have a couple baselayers that I wear for cycling in the cold that are thin smartwool, and they work great.
