Since I wanted to spend a small fortune on a new shirt, I tried this out. When first putting on the shirt felt very uncomfortable on the skin. The sutures were clearly felt and the whole feeling is not very nice. The processing could be improved so well. I was afraid afterwards unpleasant friction when running and red skin. When running but then I realized surprisingly nothing from shirt. No discomfort, no heat accumulation. So absolutely, positively surprised. The moisture transport to the outside is okay, but not overwhelming. The fit of the shirt is quite small, at 188 cm and about 96 kg weight fight I have to grab here for XL and had in the beginning still that feeling that shirt is too small, but then gave up when running. The color combination is refreshing, not too bright. Overall, the shirt can get a buy recommendation, since the price is great. One point deduction for the wear.
