I think maybe I'm allergic to merino wool. I got these long underwear sets from the Post Exchange and they are great at keeping me warm. The only thing is, they itch a bit (not that big of a deal), and my face gets red and a bit blotchy.

I'm hoping that over time I'll develop a resistance to them (why get rid of them when I got them at a great price?), or maybe I'll try organic cotton as well.
