For the hottest of the hot.
The Castelli Inferno Bib Shorts are purpose-built for the sweltering days of the Tour and the Vuelta. The shorts are constructed from non-transparent mesh fabric that keeps you cool, but also manages to provide a compressive fit to keep your muscles as supported as possible. At the core of the shorts is Castell’s famed Progetto X2 Air Seat pad –it’s a favorite from weekend crits to month-long Grand Tours. It’s topped with a soft, seamless, four-way-stretch fabric to ensure that you’ll rarely experience chafing or discomfort.
An important note on the Inferno Bibs –while the mesh panels are not transparent, they’re also not UV protective, meaning that your skin will likely need a little sunscreen.

- Q & A
very comfortable shorts
- Familiarity: I've used it several times
- Fit: True to size
- Size Bought: medium
These are very comfortable bib shorts; used them dozens of times. They are what Castelli says they are; breathe very well in hot weather. I really like the Progetto X2 Air pad; but I understand that's very subjective. I don't care for a big thick pad as some other brands have. There isn't the "compression" fit as in other typical shorts, probably due to the fabric type. As an example I also own the Free Aero Race shorts, ( same size- medium )which are tighter in the thigh than the Inferno. The waist runs the same but the inferno isn't the compression style short, which truthfully turns out to be very comfortable; you almost forget you have them on. I also really like the leg gripper Castelli is using, again very comfortable for me. I think if I were to be out there a long time I would pick these over the Free Aero simply because they're not quite as tight on the thigh. However, both shorts are premium; can't go wrong with either.
Run small and don't keep the sun out
- Familiarity: I returned this product before using it
- Fit: Runs small
- Size Bought: L
Without actually riding in these, they look good and look like good quality. The chamois feels good and contains decent padding. Unfortunately they run a bit small so I had to return mine. And then I found out that Castelli recommends putting sun lotion underneath them, so I just switched to a different brand -- I do a lot of long rides on the weekend and there was no way I was going to want or remember to put lotion on before putting the bibs on.
Great fit for me
- Familiarity: I've put it through the wringer
Tried the Body Paint bibs and the straps and legs were too small - even in XL. The Infernos are great in XL, almost disappear - in a good way (the L's were too tight in the legs and straps too short, which seems to be common to Castelli for me). I am 6'-0" and weigh between 175-180, generally wear a L bib in Pearl Izumi or Garneau brands. So you may need to size up.
