NanoFlex Fabric for Stretch and Water Resistance
Kiss3 Pad for All Day Comfort
Giro3 Ankle Grippers and YKK Camlock Zips
Minimum Seams for Maximum Water Resistance
Temperature Range: 6-18C


The fabric used in Castelli's NanoFlex bib tight is similar to their Thermoflex in that it is warm and breathable, but they apply a five phase nanotechology treatment to make it extremely water resistant.  It's not classed as 100% waterproof, but in all but the heaviest sustained downpours, the water will just bead up and run off.  This is also helped by the construction with very few seams to minimise ingress points.

Castelli's KISS3 seat pad is used in the NanoFlex bibtights, offering all day comfort thanks to its continuously variable thickness to eliminate obvious ridges created by sudden changes of thickness found in other pads.  Giro3 ankle grippers combined with YKK Camlock ankle zips provide a perfect seal around your shoecover.

The mesh bib is breathable and will sit under jerseys without you really noticing and there is reflective trim to keep you more visible when the light starts to go.

Note: Castelli clothing is sized small, Tweeks Cycles recommend you select one size above normal for an athletic fit, or two sizes above if you prefer a more relaxed fit.
