Castelli Nanoflex 2 Bibshorts are water repellent bibshorts from Castelli made from those truly wondrous Castelli materials! On a dry day, the fabric offers the same insulating and breathable properties as Castelli's regular Thermoflex fabrics would. If the rain starts to fall however, the Nanoflex bibshorts will simply repel any water they comes into contact with! This has to do with the 5-stage nanotechnology treatment they've been given. Though the fabric isn't 100% waterproof, it's still Castelli's number 1 solution for staying comfortable in wet conditions!

These shorts were made for use in wet conditions. The shorts are perfectly capable of repelling water while remaining breathable. On top of that, they can be supplemented with the Castelli Nanoflex kee- or leg warmers, should the temperatures drop even more.

Just what you need in the uk for spring.


  • Good long leg length.
  • Good grippers on the leg to hold knee warmers.

Detailed product description

Kiss Air seat pad:
Comfort like you've come to expect from the Kiss Air pad. Its soft, brushed fabric at the top, seamless construction and several layers with 2 different densities and thicknesses, make the seat pad very comfortable. A seat pad designed for optimal comfort and long rides. The seamless, antibacterial upper feels like a second skin. The seat pad consists of several densities and thicknesses, and provides support and comfort around your sit bones and perineum. The breathable fabric ensures excellent moisture regulation.

Nanoflex: This fabric is manufactured exclusively by Castelli. Its base is a Thermal Fleece fabric, which is treated with millions of nano-filaments. This ultimately creates the most water repellent fleece ever produced! Water which comes into contact with the shorts retains its drop-shape, and simply slides off the fabric without leaving a trace. Perfect clothing for wet days!
