Very warm, comfortable and well-made jacket. Fine with just a shirt down to 5c, not used in colder weather yet but am sure it will be warm enough for winter anywhere in the UK and most of Europe, North America and Northern Asia with appropriate layering.
The outer material has a discreet matte finish and the jacket itself is not overly puffy, imo, despite being very warm. The fact that the insulation is synthetic rather than down also makes it more ideal for wetter winters, such as in the UK. However, don’t feel that it is heavy duty or ultra durable so I would keep it mainly for casual and urban use.
The fit is quite generous. I am 5’5” and 12 stone with a 40" chest and medium fits well, still have room for layering. Definitely recommended, cannot wait to use it in colder climates after the pandemic.
