Nicole W.wrote a review of Columbia Baselayer Heavyweight II Tight - Women's on January 1, 2015
Familiarity: I've used it several times
Fit: True to size
I needed a warm multipurpose layer for skiing, running, etc., and these work great. They're not super warm alone in frigid temps, but they will keep you cozy on a winter run or layered under a heavier pant.
