Castelli Nanoflex 2 Bib Knicker is a bib knicker with suspenders. The knickers are made out of the special water repellent Nanoflex fabric which ensures you stay longer dry in wet conditions. The tights have a minimum of seams to minimize water leaking at the seams. These tights are equipped with a comfortable KISS3 seat pad and the mesh suspenders provide good moisture wicking on your upper body. The bottom of the pipe is fitted with a GIRO3 ankle grippers with reflection for better visibility in the dark.

The Castelli Nanoflex 2 bib knicker is the ideal knicker for cold conditions, and when rain is possible. The special treatment of the fabric ensures water remains on the fabric and then drips off. The tights are not 100% waterproof, but a better balance between warmth, breathability and water resistance than ever seen before! In combination with the Castelli Gabba 2 jacket or convertible you've got the perfect outfit for wet winter weather. Do not forget the Castelli Diluvio gloves and overshoes to keep your hands and feet dry!


Nanoflex: This fabric is manufactured exclusive by Castelli. It's base is a Thermo Fleece fabric,which is treated with million nano-filaments. What creates the most water-repellent fleece fabric ever made. Water drops remain in one piece and slide off the fabric without a trace. The perfect attire for rainy days.

KISS3 seat pad: Comfort as you're used to from the Progetto X2 Air seat pad, but at a slightly lower price. Its soft, brushed fabric at the top, seamless construction and several layers with 2 different densities and thicknesses, make the seat pad very comfortable.

Precies goed.

Heerlijke broek voor deze dagen. In de ochtenden & late middag kan het al behoorlijk frisjes zijn en dan is deze broek ideaal. Geeft voldoende warmte daar waar nodig is en geeft ook verkoeling door de driekwart lengte. Fijne stof dat Nanoflex. Ook de KISS3 zeem voldoet voor mij omdat ik geen trips maak die langer duren dan ca. 3 uur. Maat XXL, 185 cm, 80 kg, slank postuur en geen buikje.


  • Fijne stof
  • Warm waar nodig
  • Koelt tegelijkertijd
  • Prima zeem


  • Valt zéér klein dus 2 maten groter genomen.
