Overall love the fit of Castelli items. Nothing loose or flappy. In this particular pair of bib tights I did get a slight amount of bunching behind the knees that caused some irritation, though I'm hoping that goes away as I use them more and the fabric softens. Typical Castelli top-line Progetto X2 chamois is quite decent, though I think there are better ones out there for the real long miles. I am 6'3" and 175lbs and the large fits me great. The wind blocking ability of these tights combined with the light brushed insulation does what I want it to do, and these bib tights are warm when cruising easy below 40F, and warm when hammering down into the teens.
These are the tights that I wear when itï¿½s 25-35 degrees outside. Below that temperature I stay home. Excellent chamois and very good fit, just size up to your typical Castelli size.
I bought these tights to extend my riding season to when it's 35F and raining out. I road tested them today on a 70 minute ride in the 40"s with steady rain. They performed well. I was pretty dry, and warm, the entire ride. I am 6' tall and weight 172 lbs and I bought the large size. They fit pretty well, although I would like the legs to be an inch longer. That is certainly not a deal breaker. I would not wear these tights above 50F, as they would be too warm, but for cold and/or wet conditions they seem pretty ideal.
Purchased these bibs specifically for cold damp days in the saddle. They are perfect for those cold day (35 degrees or less). Great wind barrier that keeps your legs warm, but not toasty. Excellent chamois, as expected from Castelli. Sizing is European, so you may have to size up from your normal kits. Comfortable fit.
