In retrospect, I have to say, the purchase is worth it. The trousers holds far (temperatures just below freezing) warm and wears well. By this I mean both the soft inner material and the fit. Should the previously mild winter again experiencing a slump, the pants will be able to show whether it is to use for even colder temperatures. I will then complement the impressions here accordingly.
For Size: I'm 1,89m tall with 78kg and have ordered the pants in L. Top rum they fit perfectly. At length, I must say, she would have been a bit more calm. Is it in motion (ie in a standing position), it is just down to the shoes on. However, if you is in a sitting position, a significant proportion of socks is already to recognize ;-)
That was me eventually but no matter, because I'm going to use them exclusively for walking and hiking. To this end, I can wholeheartedly recommend these pants so far.
UPDATE: Since the winter has waived until now (end of February) to the correct cold temperatures, there is so far no news to report on the quality at low temperatures. But I have the pants in the meantime carried twice for cycling and have to say that it it is less suitable. At least if one takes a little more sporty in the pedals, you start to sweat pretty quickly. On top of the already mentioned problem with the low pants length. This makes cycling course then a little more noticeable ...
