Christine D.wrote a review of Patagonia Capilene 3 Midweight Bottom - Women's on March 26, 2012
I will say, these are certainly warm, and they're still thin enough to wear under a (loose) pair of pants. However, they have very little stretch to them, so if you're feeling particularly acrobatic, you may be a bit confined. They are only just barely long enough, technically reaching my ankles, though I would prefer them a little longer. I've worn them running and they do just fine, but I have yet to try them in truly inclement weather.
