1. Fit: quirky. I bought them a size larger than I wear actually. To the upper body around it fits, but on the upper arms it is too far. Overall, the interface looks a bit old fashioned.
2. Function: the jacket is lightweight, windproof and can be folded tiny. It is not waterproof (is also not awarded), not water-repellent and, unfortunately, not breathable. Especially the lack of breathability restricts the use of a rather. Ski touring and for jogging it feels more like a plastic bag. For less exercise and strenuous activities like walking or hiking, it is okay.
For me personally, the jacket can be little and I would not recommend it despite the low price.
