The quality of Gregster sports stuff I really like. I had the opportunity to try a running shorts. The seams are very well made, clean stitches and processed so that they do not interfere when wearing. Especially in endurance sports can be something very disturbing. This shirt is very well, but is probably something for the more powerful man. It is definitely not a compression shirt. However, it is loose and you can use it for any kind of sport use, as the material composition (spandex and polyester) ensures the pleasant cool effect and the sweat is equal transported. Even after repeated washing does not lose its shape and this shirt the color remains what, so I'm guessing, but will change over time yet. the large print at the front with the words of Gregster is a matter of opinion whether you like it or not. I do not mind particularly, such writings are nothing unusual. All in all a good sport shirt and hence like a perfect score.
