Baselayers(Running)

[limewave]

I'm in MI too and I agree with Zoom-Zoom. Two layers is usually good. I usually only wear one layer on the bottom unless it's really bitter cold (teens with a 0 degree wind-chill).

I think the important thing is a good pair of running gloves and a good hat.

I also have issues with my chest being really sensitive to the cold. So I stock up on toe-warmers. They fit nicely into a sports bra and keep me very comfortable during the bitter cold runs.

One thing to keep in mind is that your level of exertion has a lot to do with how warm you are. So you'll want to dress warmer for a long run than you will for a race or a tempo run. For interval days, you'll want something with a zipper that you can open before your repeats and close so that you don't get chilled during the intervals. And so on.
