    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.

    The scoop on sun and fit

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: large

    I have been using Castelli for a while and I still deliberated buying these shorts for months. Two reasons, the fit and my concerns about sun protection on long rides. I did not want to spend a lot of money and not be able to wear these bibs in the environment I live in. I live in the SoCal desert and heat and sun are a serious element to contend with. Also, my Scottish complexion means I burn, peel, freckle, and repeat.
    Fit - they are tight as expected when standing up. I wear a large and am 6' even and 178 lbs with a 33" waist. Once in the riding position they are great.
    Sun concerns - I wore these bibs this past weekend for an 80 mile ride thru Death Valley and some of the nearby passes. I did apply sunblock once before the ride at about 0430am and never again. I stopped mid-afternoon. No sunburn!
    These bibs fit great, are very comfortable on long rides, support the legs and do a great job managing the heat. Pleased with this expensive purchase. I won't be buying a new pair every month, but I don't regret the investment.

    Great in the heat

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium

    69 inches, 165lbs, short legs and a long torso is my body type, size Medium. The bibs work great. At first a little tight while standing upright but disappear on the bike. Pattern on the legs is similar to Froomey in his summer kit so u have very small holes with skin color showing thru but nothing revealing or scary. Progetto X2 Air chamois is great and made my first long ride in a while comfortable. If u live where it's boiling hot in the summer like I do I would recommend these bibs. Plus they're Castelli so you can't go wrong!!

    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.
