Jay F.wrote a review of Castelli Free Aero Race 4 Kit Bib Short - Men's on June 2, 2019
Familiarity: I've used it once or twice and have initial impressions
This season I bought 3 pair of Castelli brand bib shorts and one pair of long pants for winter riding. I find the quality of everything I purchased to be extremely high. I've now worn these bib shorts twice and they are extremely comfortable and fit well. The pad is the best and most comfortable I have ever worn. The product holds up well after washing. I also bought a pair of the top of the line bib shorts and those are fantastic as well. I considered Assos and Rapha, but the pricing at the time was excellent. Also, have seen many in my riding club wear Castelli, so that was a strong recommendation for me. Glad I bought them. As far as sizing, i usually wear a large in Pearl Izumi & Voler and was told to take an XL. The people I dealt with at Competitive Cyclist were right and I'm happy with the XL. So, remember the sizing runs small. Go up one size for the best fit.
