    I've got this Castelli bib short, some mid-tier Pearl Izumi bibs, and recently received an Assos pair (Mille summer GTS.) As expected, the fit is tight, so I (6-2, 190 lbs) ordered an XL pair, which fit nicely. I like (almost) everything. The design and materials are excellent, the pad is a bit thin, but has nice progressive density, so it provides good support. Overall, I really like it, but it could be better. The straps are very narrow and don�t always stay flat. That said, they are very soft and light, so I don't really notice them. They feel good, but might bother people who are very particular. The most significant issues are in the sensitive areas

    The area for the genitals is very tight. This isn't related to size. When we ride, blood goes to the legs. The pressure of the shorts further squishes everything. I find it uncomfortable on about 75% of my rides. Similarly, the pad is tight at the perineum. I have saddles with cutouts, but if the pad is too thick and stiff to take advantage of the cutout, it limits how aggressive you can sit on the saddle. By comparison, my new Assos shorts provide more room up front and also have a cutout in the pad.

    But the Castelli shorts have some wins over the Assos pair. I get zero rubbing of stitches or edges with the Castelli bibs. The Assos bibs have a couple of potential chafing or bother for me. So the search continues. If I could get the Castelli bibs with a cutout in the pad and a bit more room up front, it would be perfect.

    Good quality nice bib shorts

    These bib shorts are consistent with other Castelli bib shorts. This model tends to fit a bit tight, in a good way. The color was advertised as blue, but the product is actually gray. It's an attractive short. Castelli tweaks the designs often--about every year?--so this is another tweak, and perfectly good.

    After years of resisting bibs because there's no ez way to relieve yourself I tried these. Outstanding fit, finish, feel, and ease of relief! Love these bibs and all Castelli products. I ride about 150 miles a week with regular centuries.

    Top level bibs
    rating
    by Anonymous

    Very high level of quality and overall comfort, fit for me is outstanding. Only complaint is the straps kind of roll up very thin and are uncomfortable unless you take the extra minute or so to flatten them out before your ride. Also, they do run quite small, best to size up.

    Nice bib short but

    These are my favorite bibs, I ride them on centuries all the time. They are mostly comfortable except for the fit around the bits and pieces. Like I said I ride these all the time on long rides, great pad too, it�s just a little tight in the front.

    Beautifully made shorts

    High quality shorts that prioritize low weight over durability. These shorts are gossamer thin. I poked a small hole in a leg that I had the tailor fix for $20..

    The pads seem to extent more laterally than Im used to.

    Next time I may select a lower level pair of Castelli bibs for thicker more durable material.

    Fantastic bibs, every bit the quality and comfort of Assos at a fraction of the price. Only caveat is they run small. Im 59 155lbs and Im a large.
