I have this training shirt of Gregster, a new brand, now worn four times in the gym and as often washed. It still looks like the first day. The seams have been really well finished; everything is there, where has to sit there. In addition, the fabric is really pleasant. If you have not worn often a functional shirt (and certainly not long-sleeved), it feels a bit strange at first, because it is so tightly around the body. However, as previously written other reviewers, the shirt is the waist a little too big (and I already thought it was just me because of a possibly strange physique ...). Thus, it fluttered and less bother, you should put the shirt in these pants. Otherwise the substance is but with every movement. He donates it releases heat and absorbs sweat, which quickly dries due to the materiality of the long sleeve tops. Of course this is especially handy if you want to put on the training shirt tomorrow again and evening durchwäscht it short. It looks after then from virtually the same as before. Pulled threads and a cracked surface acting, as I discovered it very early with my old spandex shirt, have not yet been felt in this product from Gregster. This is another practical component associated: Through the processed spandex shirt that never seems to go out of shape, is saying that you do not need an extra iron. All in all I really wear this functional shirt very much, although it has long sleeves and belly is a little too far. I prefer the otherwise rather Sleeveless Tank, if I go to the gym. But with this shirt I like to do an exception, because it feels like a second skin in the shoulder area - four stars.
