I prefer the Castelli bibs with the KISS pad as it is my go to for rides in the 70 mile range. The material and craftsmanship are excellent. Drawback: minor, but actually prefer the more traditional bib cut in the front . I need to size up for Castelli bibs. I order the XL. I'm 5'9" and weigh 177.
One of the best bibs. The chamois is superb. Comfort for all day ride.
