Coefficient Fleece Jacket - Women's is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Sizing completely off I own the 2016 version of this jacket and since I loved it, I decided on repurchasing one this season. I am 5'6, 121 lbs and my previous coefficient in size S fits like a glove, so after having reviewed the size chart, I ordered the same size. Unfortunately, the jacket looks and wears more like a size large; not only is the torso extremely long (it falls more than 2 inches below my hips on the front) but the back is so baggy that I highly doubt that even XS would fit me correctly. The color (Rhone) is lovely and the material and construction are top notch, but I will have to return an otherwise awesome jacket due to poor sizing.
