Castelli
Women's Nanoflex Donna Bib Tight

Nanoflexing your way through winter.

At this point, most people have experienced the warm, dry comfort that Nano Flex warmers provide. Nanoparticle waterproofing is quickly helping us gain ground in our ever constant struggle to combat the elements while riding. Castelli's Women's Nanoflex DonnaBib Tight combines their water-shedding Nanoflex fabric with a minimal seam construction to tighten your defense against wet weather. Up top, comfortable bib straps provide additional protection from the elements while also preventing cold spots. GIRO3 ankle grippers are designed to seal around your shoe covers, but YKK® camlock ankle zips still make these tights easy to get on and off. A KISS Air seat pad offers all day comfort with its anatomic shape and continuously variable thickness for natural-feeling contours.

Reflective details on the legs and ankles increase your visibility in low light.

Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.
