The substance is - as some reviewers have noted here - really very thin. Although you can not see through (I also navy blue chosen in a light color, I would it not put forth my hand in the fire), but that part fluttered around at one, making it possibly acts like a better pajama bottoms. Although the pants in one size fits broadly (have 40/42), but the federal government is far too broad. Even if I as much as possible pull the lower edge of the collar down, the edge goes up up too far, so I automatically get the association to a maternity trousers. If one turns the edge it comes reasonably. The length fits in a size of 171 cm just like that. Expensive pants was not and the delivery was very fast, the part was only unnecessarily large packaging. I will keep the pants for home and the garden, but for something else, I will not use them well .... and I would buy under any circumstances again.
