Punching way above its weight class, Castelli's Tutto Nano Bibshort is the cycling tight that's literally good at everything.

A decade in development, the Nano Flex 3G fabric is Castelli's best all-around fabric for winter tights: warm, stretchy, luxuriously soft, and highly breathable.

While other companies utilize chemical water-repellent finishes, Castelli labored for more than 10 years to create a nanotechnology mechanical repellency to enhance a chemical DWR finish. The result is a drier and more dynamic riding experience.

But don't think of the Tutto Bibshort as just a niche rain tight. The Nano Flex 3G fabric doubles as a great dry-weather option, with the reduced-seam, anatomical cut making it extremely comfortable during both casual commutes and longer expeditions alike.

At the Tutto's center is the pro-level KISS Air2 seat pad while a mesh bib that shakes off moisture and taped knee bands that hold their grip bookend the extremities.

If you're winter riding calls for unpredictable conditions, find your flex with the Tutto Bibshort.

Features & Specs:

  • Versatile bib great in changing weather conditions
  • Nano Flex 3G fabric is exceptionally warm and soft yet with even better rain protection
  • Reduced seaming for improved comfort and fit
  • Mesh bib straps don't hold moisture
  • KISS Air2 seat pad for long-distance comfort

  • Claimed weight: 278 g

Extremely comfortable

I got these on sale, and I'm glad I took the chance after reading some of the comments and doing a bit of research on them. These are the most comfortable bibs I have bought from Castelli. I do a lot of indoor cycling on zwift, and let me tell you... The most I would do was half hour on the bike, and since receiving these, I have gone up to to an hour maybe more pain free. You will not be disappointed in these if you like comfort and enjoy long rides.

Size up and stay happy!

Chamois is very comfy and have done a century Ride without any uncomfortable or annoying shifting. Material feels great and unnoticeable. Great logo reflections and wears very well.

Exceptional fit, comfort and warmth in a cold weather bib short for Spring and Fall riding.

Castelli has created a bib short that could be worn under a lighter pair of tights in Spring or Fall or potentially a very cool Summer morning. They are exceptionally comfortable and I have worn them on fifty mile rides with little complaint form my backside. My pair of size medium fit my 5 foot 9 inch frame nicely. I usually weigh between 160-165 pounds. If you are tolerant of "lower" temperatures these would be excellent for 50-60 degree rides all by themselves. With all my new Castelli gear I have stopped putting them in the dryer after washing even on the super delicate setting. Read the directions for yourself and given the amount of money involved I say err on the side of caution. I wish I could put them in the dryer but I'll trade off the time between uses to have them last longer. I like them that much.

Great Winter Shorts!

Have done several rides in these so far. The fit, cut and the chamois are perfect! They provide good warmth. I don't ride much when it's less than 40 but I think I'd still be comfortable in them at even lower temps.

Great for cooler weather!

Great for cooler weather! I was looking for a midweight bib to get through the winter and this definitely was a good choice. Fit and overall construction are what I expect from Castelli and these are my go to shorts when the temperature drops.
