Aria Shell 2 Jacket - Women's

What Our Gearhead® Experts Are Saying:

"This jacket is one of the lightest and most versatile pieces in my kit. It fits close without feeling restrictive, and I love how breathable it is. Perfect for early starts or descents—you’ll forget it’s in your pocket until you’re thankful it is."

The Aria Shell 2 Jacket is a streamlined, packable wind shell built to extend your riding comfort across seasons. Designed with a windproof microfiber front and sleeves, it shields your core and arms from cold air while maintaining breathability thanks to stretch mesh panels at the sides and backs of the sleeves. The tailored fit hugs the body for a flap-free ride, even at higher speeds or in the drops.

With a weight of just 100g, the Aria Shell 2 disappears into its integrated stuff sack, making it a minimalist solution for unpredictable conditions. The two-way YKK® Vislon® zipper allows for quick mid-ride ventilation adjustments, while reflective Castelli logos offer low-light visibility when dawn patrols or dusk returns stretch your day.

Perfect for cool-weather transitions, pre-dawn warmups, or alpine descents, the Aria Shell 2 is a highly functional wind shell that balances packability, protection, and aerodynamic fit for performance-focused road cyclists.
