At 6' 2" 175lb I got the extra large size based comments by other raters stating that Castelli typically runs a size small. The overall length seemed good, but the waist and hip area were a bit loose once on the bike. Perhaps a large for my build...would probably be slightly uncomfortable to stand in, but would feel fine once on the bike. The bibs leg length cut was shorter than I was expecting. I spent over 2 hours on the bike and found the pad to be comfortable . My opinion is Castelli makes great looking gear but I don't get the fit with comfort that I'm looking for with my build.
