Very good quality, I was a little bothered by the cord-like detail on the edges (neck and sleeves), but I believe I will get used to it.
As for the quality, it seems quite good and durable. In terms of fit, it is comfortable, slightly loose without bagging or ruining the appearance of the shirt I wear on top (I am 1.71m with a regular body and wear size M).
I will provide further feedback after wearing them more.
