Good quality nice bib shorts
by SFRonH
Cycling Enthusiast
San Francisco, CA
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.

Best IMHO
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
by Anonymous
Cycling Enthusiast
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
3 of 4 customers found this review helpful.
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.

Excellent bibs

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.
