The high cotton content (95%), they are very comfortable to wear, which provide 5% spandex that the briefs retain their fit even after washing.
The briefs are easy to care for, they can be washed at 60 degrees and tumble dry without warping or enter into it.
Qualitatively, the briefs are (as of Schiesser usual) absolutely high-quality workmanship, all seams are sewn clean and in no way "disruptive" or "scratchy", the Bund is beautiful elastic and provides a good grip without pushing it.
The fabric feels very thin and soft, you can hardly feel it.
The briefs meet all my expectations for quality underwear, my daughter finds them "ultra comfortable" and therefore I can recommend them without reservation.
