I'm curious, in cold weather, which fabric keeps you warmer? Wool, polyester?

Polyester or a blend of polyester and rayon is the best bet in cold weather. It doesn’t have the natural thermal protection of wool, but it's highly resistant to pilling.  Wool also retains more body heat than polyester, but it's so soft that it's hard to wear.

Polyester can be great, although sometimes it doesn't breathe very well. You did mention having a blend.
