Castelli Tutto Nano 2026 bib shorts

Our Nano Flex 3G fabric is the result of a decade of development. It's our best all-round fabric for winter tights: warm, stretchy, luxuriously soft, super breathable and to top it off, it features our water-repellent finishes made with third generation nanotechnology. While other companies use simple chemical water repellent treatments, we have created mechanical water repellency using nanotechnology to enhance the chemical DWR finish. You'll be warmer and more comfortable. While this tight features our latest water-repellent technology, don't think this is just a niche rain tight. The fabric also makes it excellent for dry days and the reduced seams with anatomical cut make SIt's very comfortable. We used the KISS Air2 pro pad, mesh braces and ankle zips. These tights are great in all weather conditions.
