Castelli Nano Light Pro Bibshorts

Designed to wear on your spring training rides, Nano Light is at the cutting edge of fabric technology. Nano Light is just like Nano Flex but without the fleece lining. We go into the science in more detail below, but the result is that Nano Light actively repels water, to keep you drier for longer.

Nano Light is coated with millions of microscopic nanofilaments. This nanotechnology treatment causes water to bead and run off. Seams have been minimised to keep water out. The Nano Light Pro bibs shorts aren't 100% waterproof, nor does Castelli claim that they are. They will, however, keep you drier than virtually any other shorts out there.

The Nano Light Pro tight features the Kiss Air seatpad, incorporating many of the features of Castelli's top-of-the-range chamois. In any cycling garment, comfort is paramount and the anatomical shape of the Kiss Air pad ensures maximum comfort, no matter how long you're on the bike. Dual density foam is used to provide variable thickness - padding where it's needed and less where it isn't, to maximise your freedom of movement on and off the bike. Finally, a brushed microfibre top layer, with superior softness and an anti-bacterial treatment eliminates chaffing and saddle sores.

When getting those extra training miles in means venturing out in the dark, reflective logos will help keep you safe by making you more visible to other road users.

When winter turns to spring, the revolutionary Nano Light Pro bib shorts will have you prepared for anything.

With roots dating back to 1876, Castelli has been at the forefront of fabric technology for almost 40 years. Alfredo Binda, Gino Bartali, Fausto Coppi, Jacques Anquetil and Louison Bobet were but a few of the legendary athletes clothed by Castelli. More recently, Bernard Hinault wore the first windproof jersey when he won Fleche Wallone. Castelli made that too!
