Erica D.wrote a review of Columbia Baselayer Heavyweight II Tight - Women's on December 12, 2016
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
Works very well. I wore them under leggings for a 5k in 40ish degree weather and I was warm. Fit is true to size. I wear XS in Colombia and these fit well. I ordered them for a ski trip to Montana in January, I have high hopes for them!
