Mercerized cotton is not only noble, it also hard to believe that it is cotton. Slightly shining, elastic, very slightly transparent. The build quality is top, here fits every seam. And the size is perfect. Hanro has long been my favorite, when it comes to nightwear and underwear. And now even with outerwear.
Edit: All too soon lost the collar of elasticity and made naught the noble impression. I am now switched to Zimmerli. The quality is there much better, with the same material
