Overall, a functional shirt that has my expectations completely. It wicks sweat away from excellent (I sweat pretty quickly and strongly), sticks after heavy sweating not stick to the skin and is comfortable to wear. When wearing only an indication: breast and Bauchbehaarung should shave or leave uncut stand, because the shirt with hair stubble is still unpleasant on the skin. The quality of the material is good, but I can say nothing about the longevity. I would just want to give it up to come with Velcro closures (eg of bandages) on the shirt, because I suspect that then form pulling threads. The printed applications (Nike swoosh and product name "Dri Fit") probably will not hold for too long, but that is in such a shirt not matter anyway. To fit: I have read that one should rather order one size smaller. I wear L / XL and L was clearly too tight and pinched me under the armpits. I can therefore not confirm and tend more to choose the standard size (or at intermediate sizes the greater), since the shirt is also very tightly.
