The sizes in "The North Face" fall a little bigger. Since I am a "XL" rack, I have decided for the fleece jacket in L, and have to say that it fits perfectly. Above all, it fulfills its function, it keeps you warm and is breathable. It is recommended as a middle layer at temperatures below 10 degrees very (over 10 degrees is then under the hardshell too warm). But you can easily carry such as the upper layer even on dry days. The feel is very comfortable and luxuriously soft.
