The shirt fits perfectly, is well made and the fabric is really comfortable. The size guide worked perfectly for me as a 1.77m / 70 kg male - size s.
The order process was a bit strenuous, as two articels got canceled due to a wrong inventory. This resulted in a long delay in delivery and first i also wasnt able to got a reply from the customer support. After the first reply (which was a little bit too late for my taste), everything resolved quickly. The customer support is polite and caring, they apologized for the hickups and also threw in generuous compensation. I think that was an unfortunate, rare experience and i will certainly order further products from rungne in the future.
