I like these shorts, right along the lines of the lesser Velocissimo Due and Equipe shorts, but with a lighter fabric. The big change is in the chamois to the "advanced" Progetto X2, but it doesn't do it for me. It's a very large chamois, not really an improvement on the Kiss3, just a bigger is better and we put gel in it approach. Everything else about the short makes them perfect as the go to bib, but I'll save a little money and keep getting the velocissimo's. True to size, so they run small by compare to most brands, I wear a medium in Capo, Pearli, LG and most everything else but a large in Castelli. The fit is snug, but it's as close to a race product as you can get without being for racing.
