I use the shirt now for several weeks and wear it while running always under a sports jersey and am very satisfied. It fits comfortably fit the body without constricting like a compression shirt. The soft material absorbs sweat well and passes it on. At high temperatures, so sweating is tolerable and at low temperatures it is cold not. I'll take the shirt to be hardly noticed, only the positive features. Is also pleasant that the shirt unlike some others that can only be washed at low temperatures, assumes no lasting odor.
The price / performance ratio I judge to be balanced. One can certainly significantly more for functional underwear spend, but also significantly less. The wide temperature range in which the shirt is comfortable to wear, justifies the price in my eyes.
However, one weakness has the shirt: The white mesh zones are extremely sensitive. Here I made the mistake the first off that I have resorted to the mesh fabric, and have torn a hole with your thumb. But even with the patched hole the shirt bears still very pleasant.
