First: The jacket keeps as promised water and wind gusts and heavy rain from also are no problem. The processing of the jacket is very high. In addition, I am a person who often gets in the daily shuttle by different temperatures (walk, tram, walk, train, walk) sweat. This jacket has greatly eased and I can on short train rides also keep on time without being directly in its own juice. Unfortunately, I had the jacket so far only once at low temperatures (5 ° C) and have found myself in motion I have not frozen, although I including wearing only a T-shirt. I assume that it provides sufficient isolation even in freezing temperatures. Both the inner and the outer jacket can be worn separately and wonderful. On warm days of rain the outer jacket is sufficient to cool but dry autumn days reaches the cozy inner jacket. By 3in1 function can this jacket wearing all year round. For me a worthwhile investment.
