I'm 6'3"/195 lbs with a 34" waist and ordered these in size Large. Tried them on and found them to be about a size too big. Unfortunately, they are out in Medium.
I found these to be very high quality and would be a great winter bib tight. They are fleece lined throughout, even on the inside of the bib straps, which is a nice touch. Zippers on the leg openings and the top center of the bib are a nice features also.
