The shirt is very, very light and airy. It is not tight and you hardly feel it on your skin. If you do your exercises outdoors, you will love it when a breeze blows through the shirt and you can feel it on your skin because it is so light and airy. You won`t sweat in this shirt during normal exercise. The sizes are well adapted to European customers. I can only recommend the shirt because you should concentrate on your exercises and the shirt should not distract you by rubbing, stretching or anything else.
