I really am not inclined to excessive perspiration, on the contrary, during sports or on the sunny beach I'm usually the last person who sweats. Rather, I overheating internally. Made from 100% polyester, however, manages to make a T-shirt worn under abbekommt sweat stains in normal everyday life. I knew not at all so far. In no other jacket came or does that happen. Moreover keeps the jacket smells extremely - which is probably normal in clothes without wool. I would have to wash about every few days. This keeps them but not out, are formed lint. But I feel anyway so uncomfortable that I already do not wear after a few hours in this jacket. A bad buy so. With the thin jackets Jack & Jones on the other hand I am very satisfied. In this model here is simply the material is a mistake.
