I'm wearing this t-shirts now for 3 years and am thrilled. As so often described to me, the shirt has a very good fit and wears incredibly pleasant. At a height of 1,73cm and a sports figure I have, however, changed after a while of the 48 (M) to 50 (L), as deodorant residue in the underarm area became noticeable and the size 50 then no longer quite as closely abutted on. It is actually the most comfortable shirt, which is known to me!
