Very trendy shirt, which visually looks really good. The quality is functional and well made. The material extremely light and fine. The color is very tired, the seams are colored funny. The size is quite scarce. The shirt is in Gr. M and fits well, even though I actually Gr. S Wear. Surely there must be sitting very close to the special compression to stimulate. But one should not expect too much, it is not a medical or scientific results product. The price I find appropriate.
