I bought this jacket for a visit to Europe in May 2019. Europe was quite cold for me, around 12 degrees (max) and -10 degrees (min). This jacket worked perfectly for the weather. It has two layers and based on the degree of cold you are subject to, you can use the layers such that you feel comfortable. The jacket also comes with a removable hoodie. Obviously, the jacket alone will not suffice for extreme temperatures. Please use your best judgment and layer yourself (use multiple times shirts or thermal wear) in addition to this jacket. I had two layers under the jacket which kept me warm in -10 degrees.
