The pants I wore in my last winter vacation. After half an hour my legs were wet with sweat and dried out the whole day! not more from. Even wearing functional underwear could not change this situation. The functional underwear was also quickly wet. On demand at Killtec if I handled the pants may be incorrect, or if it were a quality defect, I have received no reply. So I'm assuming that these pants were not mishandled and the quality is poor ist.Fazit trouser absolutely not recommended!
