I've tried almost every high-end bib short and so far the body paint takes the prize. A key for me is the fit, how the chamois feels like it becomes part of your body. Everything is perfect, but ordering at least one size up is essential.
--I'm 5'10" & 147 lbs and I had to get a MEDIUM.
If you ride long and have issues with comfort then look no further. I plan on riding the annual double century again in these babies to really put it them to the test (my LG Mondo's didn't do it for me last year).
