For the sport, I have sought the right sub-pull toys. The size is always a bit tricky. In 1.71 - 70 KG and narrow physique I thought the M should fit. However, the on and off designed itself as "rice test" for the substance so much you have to stretch it. However, the better sitting behind the shirt on the body, as it indeed should be. When do I have to take off so much pull on it to get the shirt over his head that I'm always afraid to the substance. But it's been all good and the great characteristics of the shirts in sports are excellent. I always carry it with the football and the climate is just great. The seat is also very good and after a short time does not even notice you the shirt.
All in all, what I wanted and for 22 euros definitely a great price.
