I (186 cm/77 kg) chose an L for a slightly wider fit as a belay jacket over other layers. The back and arms are long enough and the fit is great overall over other jackets as well as over just a base layer.
I couldn't test the jacket too much so far but it seems to be plenty warm for my use case (standing around in just below freezing temperatures or moving when colder in high mountains).
It would get 5 stars if the down part in the front was baffled instead of stiched trough.
