I ordered these pants only in size M because pants from other manufacturers fit in this size. However, this was not too tight but narrow so Thi body. I prefer to sleep but not so ehr tight-fitting clothes, so I ordered the pants in size L. This now sits a little further cut. The fabric itself is very comfortable on the skin and is very light. Since I prefer cold to sleep, it does not bother me in the winter that the trousers not very warming, as it is written above, not thick or is roughened. Therefore, I can well carry them in winter and probably also in the summer. Also at the breakfast table you can sit well with this and are well on the sofa, so that they no longer like to move out.
