I ordered the size M with my ~ ~ 176cm and 73kg. Jeans (in winter) are usually 32/30 with me, so I have some breathing room with functional underwear. With these pants I ordered good reason M, because I wanted it a bit tighter. In sports the trousers should be cut and "rumflattern" not too much.
In short, they fit perfectly and looks great.
Used them regularly for running, cycling and now and then just like that, because they just fit perfectly. In cold weather, especially when riding a bicycle, but I would baselayer or function trousers underneath tighten. Otherwise it is quite cold (and the pants quickly wet).
Strong buy recommendation. Pay down my pants again soon.
