The Thermohose doing exactly what they should do: protect the legs against cold wind, so that one even at low temperatures (+ / - 0 degrees) can cycle right temperature. I'm 1,88cm long, slender and have size M purchased. For me, the trousers fit perfectly around the legs. One forgets the pants easy. The comfort is high. The only minus is the length of the carrier. The carriers are just too long and, therefore, the pants hanging unsightly after the ride sometimes. This is not really nice, but does not diminish the wearing comfort. The pants have no seat insert, so it is advisable to wear a cycling shorts or similar underneath.
I'll let me shorten the carrier at the tailor. Then the pants is really perfect.
