Castelli's Tutto Nano Bibknicker 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 bib knicker features Castelli latest water-repelling technology, don't think of it as just a niche rain garment. 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 wide flat cuffs have great stretch and hold. Reflective logos and highlights help keep you visible when you need it. Enjoy the protection and warmth of the Tutto Nano Bibknicker as often as you can.
