Castelli Tutto Nano Bibtight

Castelli's Tutto Nano Bibtight delivers great fit, feet and function with protection and true cycling design. Nano Flex 3G fabric is the result of a decade of development. It's Castelli's best all-around fabric for winter tights: warm, stretchy, luxuriously soft, highly breathable and on top of that it features the proprietary third generation of nanotechnology water-repellent finish. While other companies are using simple chemical water-repellent finishes, we create a nanotechnology mechanical repellency to enhance a chemical DWR finish. You stay drier and more comfortable.

Even though this tight features Castelli's latest water-repelling technology, don't think of it as just a niche rain tight. The fabric makes for a great dry-weather tight, and the reduced-seam anatomical cut makes it extremely comfortable. The designers spec'ed the pro-level KISS Air2 seat pad along with a mesh bib and zippered ankles for easy on and off action. Reflective logos and highlights help keep you visible when you need it. Enjoy the pure 3-season cycling capabilities of the Tutto Nano Bibtight.
