Body temperature:
Admittedly exercise Running at almost 30 degrees in the sun, because the sweating is already pre-programmed, but in pure microfiber do not mind. Despite the low cotton content the wet shirt clung to the skin, what I have found to be unpleasant. In this respect I can, zuindest in extreme conditions, not to speak of a comfortable fit. In colder weather, or in the gym that might be better.
Optics and fit:
It is simple yet beautiful. Verges are always beneficial. It turns out normally and has a good cut. Even after the first wash, it was not warped.
Care:
As all-iron (like microfiber) I would not call the shirt, but it is not as wrinkled from the machine such as pure cotton. Should anyone really want to do without ironing, probably falls not to so.
Conclusion:
Who loves pure microfiber, will probably remain, who has taken to sports cotton shirts, will be thrilled, because this shirt is soft feels like pure cotton, also lighter (thinner) than pure cotton, but less wrinkles.
