Unfortunately, the quality is extremely poor. Reason: Fit extremely bad! Have eigentl. never had problems with the fit with M, because I am slim, 176 tall. The underpants are on the field of calves too big and much too tight on the legs. Already when tightening (not violently) the first seams were already on. The cheap material itches everywhere. Absolute quality disposable. I've thrown away after the first few, because they really are not suited to more. For this, however, the underpants are too expensive.
