What's Cool In Road Cycling

New Product Technology from Castelli and Gore

On December 1 W.L. Gore and Associates will announce a new product technology that brings unprecedented levels of durable rain protection with the lightest weight Gore-Tex fabric ever.


The new “GORE-TEX® Active products with a new permanent beading surface” is an innovative fabric construction that eliminates the textile on the outer face of the fabric, resulting in a 2 layer fabric that is lighter weight and doesn’t absorb moisture on the outer face. Water rolls off, you stay drier, and it all packs away in sizes that were impossible until now.


Gore is launching this new technology with just 5 partners: Arc’teryx and The North Face in outdoor, Gore Running Wear in running, and Castelli and Gore Bike Wear in cycling.

Castelli’s take on this new technology is of course made for the cyclist seeking maximum performance. The Castelli Idro Jacket weighs a mere 155 grams in size Large and folds down to fit in half a jersey pocket. When the rain starts you have full Gore-Tex® “Guaranteed to Keep You Dry” protection. We’ve designed this jacket with an emphasis on light weight and minimum bulk, so it has a minimalist construction as well. But you still have ample reflectivity for safety and a zippered opening for access to your jersey pockets. The anatomic fit which is optimized for a performance riding position will prevent the jacket from billowing and slowing you down.


The Castelli Idro jacket is aimed at the Gran Fondo rider or the big mountain rider who will encounter the sudden storm in the mountains and demands maximum protection. As such, the jacket will be available for the Gran Fondo season and the rides in the big mountains.
