Size M fits me here, as usual, very good. Some other briefs are too far on the legs - but this slip fit for slim legs. Also comfort very well: no twinge or is too tight - just right. The material (47% Modal, 47% cotton, 6% spandex) feels on my skin very pleasant to. The slip also has after a day still the same fit as the morning.
For people to whom it is important that the genital area a neat bulge can be seen: this is not the case, these briefs makes everything a little more precisely.
The pressure I find beautiful, but that's a matter of taste.
