CASTELLI BETA RoS Jacket Green/Red 2023

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.

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 Castelli made this jacket.

They used the lightest, stretchiest fabrics they 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 Castelli'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.

Castelli'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.

Nano Flex
Exclusively engineered by Castelli. Castelli take their 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.

Polartec NeoShell
Polartec NeoShell is the world's most breathable waterproof fabric technology. For years the outerwear industry has prioritized excessively high waterproof ratings that sacrifice the breathable performance needed during physical activity. NeoShell provides the strength and durability of a weather protective fabric, while still allowing dynamic air exchange and comfortable full range of motion.

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

Rosso Corsa
Castelli's Rosso Corsa label is only applied to the highest-level products they 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.
