I'm 6'4" 205 lbs fairly muscular. I had a hard time finding bibs that were long enough in the inseam, with long enough straps but also form fitting enough to work well at my height. The long, wide, stretchy straps on these bibs make them ideal for a taller rider. I'm wearing a Large (L).
The fabric also breathes great, and the chamois is the most comfortable I've tried (including Pearl Izumi P.R.O., Capo Martello). Reflective highlights are a nice touch.
