What It Is

This thin wind and splash barrier provides a surprising amount of warmth while being so light and stretchy you'll hardly notice it. Race fit for performance on fast autumn and spring rides on any terrain.
Polartec® NeoShell®

Lightweight fabric designed for clothing worn during physical activity of long duration and intense effort in extreme conditions. Extremely breathable, waterproof and windproof. Offers maximum freedom of movement and protection.

RoS - Rain or Shine

We’ve engineered RoS as the no-compromise best clothing we know how to make for dry conditions, and then tried to make it as close to waterproof as possible without sacrificing breathability and ventilation.

Nano Flex

Exclusively engineered by Castelli. We take our thermal fleecy stretch Thermoflex fabric and coat it with millions of tiny nanofilaments to create the most water-repellent fabric finish ever. Drops of water stay as spherical balls on top of the fabric or bounce off the fabric without leaving a trace.

Rosso Corsa

Our Rosso Corsa label is only applied to the highest-level products we make. Every thread and fiber, every curve and contour is obsessed about. Rosso Corsa represents a categorical breakthrough in cycling innovation and the meticulous craftsmanship you expect from Castelli’s performance-enhancing apparel.

As summer turns to autumn we still have a few months of amazing riding, but when we have to start dressing warmer we miss the freedom of wearing just a jersey. That's why we made this jacket. We used the lightest, stretchiest fabrics we have to make a jacket that cuts out most of the wind, remains highly breathable, provides remarkably high levels of water protection, and just basically disappears so you don't really notice it. This is a performance piece, so we've kept it focused on the task at hand. There's nothing superfluous on it, unless you consider the big reflective panel on the back to be unnecessary. We don't. We've given it a close-to-body fit so there's no fabric flapping in the wind, which also helps keep the jacket warmer. The pockets are generous and easily reachable, the zip slides easily, and the logoing is discreet.

Ideal para otoño

Es una chaqueta cortavientos muy ligera. Es muy elegante y bonita. Aísla bastante el aire. La he probado con maillot de manga corta debajo en bajadas de montaña y no he sentido nada el aire. Solo añadir que las mangas son muy estrechas por lo que es conveniente coger una talla más. Es un cortavientos muy bueno para otoño y primavera o con temperaturas no muy frías.
