Use the jacket for hiking, cycling and other sports activities at about 15-18 degrees and windy weather, so that the body can not cool down by that wind. The jacket is windproof not 100%, but it is also my right as against some few air is nothing, as long as you do not feel the train and the major part is kept away. Light rains of about half an hour, the jacket endured perfectly. Unfortunately, the interface is not optimal for stout muscular people, as I have at 1.75m and 89kg at the shoulders and chest in size XXL little space. It's just like that. The advantage is that the jacket is long even with XXL and I therefore work not in the jacket as in a dress.
