I normally wear a Medium in bib shorts, but had to get a Large for these. Maybe they are more aligned with European sizing, I don't know, but they fit very well for me. The legs are a bit long, only about 2 inches from my knee to the bottom of the shorts, and I'm used to about 1 less inch of leg length, but the trend now is a longer inseam. Overall they are comfortable, though I have worn more comfortable shorts (which is all down to the chamois in this case). I would rate them as 8/10 for chamois comfort and I have 2 pair from another manufacturer that are a 10/10 for me. Most chamois I have are 8/10's. They are comfortable, but not like a brand new recliner after a 4 hour ride on a Sunday afternoon, if you know what I mean.
Overall, they are a good pair of shorts, and chamois comfort is 75% up to the individual. The materials are nice, though may be a little fragile around the inner thigh and front groin, but that is also what makes them breathable. the outer panels are a different material and are more durable.
p.s. I am 5'11", but I have slightly longer legs and shorter torso for my height. 6'0" if my torso was proportionately correct.
