I get it now, Cheri.
Perhaps the thin neck gator pulled up over your mouth might help to warm your breath as it comes in. You might sew two gators together to make one tall one that can go up high.

If you do ever get the merino tops, I can tell you that the Ibex run just a bit smaller/skinnier than the SmartWool ones.

I wear glasses, and I do find that sometimes my eyes get cold in the downhill winds and they get teary. Usually in the beginning of my ride only so far. I expect more problems as it gets colder, especially since my frames are metal not plastic.
My nose always runs when I'm biking. I think it has to do with the wind as I ride. I've always found that it runs even MORE if I blow it. It seems to irritate my nose linings so they try to protect themselves with yet more mucus coatings. So I just sniffle it in and swallow (I figure it's already in there anyway!)
