Train Through Anything

We initially developed our Nano Flex tights to help you get through the occasional rainy day of training. But you asked for more, so here it is: the extreme-duty Nano Flex bibtight. By putting an extra layer over the thighs, knees and bum we're able to significantly increase the rain protection while also blocking a bit more wind. We've made the lower inner leg completely waterproof, since this was usually the first area to soak through with our Nano Flex tights. And because these tights are going to see heavier use, we've also upgraded the seat pad to the Progetto X2 Air, so you're ready for long rides with a high probability of rain. 


  • Nano Flex fabric gives outstanding warmth and stretch with water resistance
  • Minimal seams for maximum water resistance
  • KISS Air seat pad for all-day comfort
  • Mesh bib straps for breathability
  • Reflective screen-printed Castelli graphic on both legs
  • GIRO3 ankle grippers lie flat and seal around shoecover
  • YKK® ankle Camlock zippers with reflective tape for high visibility

Occasionally, without notice, manufacturers change product design and/or specifications.
