Castelli - Aria Shell 2 Jacket - Men's - Silver Grey/Dark Grey - 2026

Castelli - Aria Shell 2 Jacket - Men's - Silver Grey/Dark Grey

The Aria Shell Jacket has always been one of the most functional pieces in Castelli's lineup. Now, it's better than ever.

Castelli has refined the fit for improved ergonomics and added reflective details with Castelli's new logo and wordmark, making you more visible without compromising style. It's still impossibly light, still blocks the wind where it counts, and still breathes thanks to the mesh side panels. But now it fits even closer, thanks to updated stretch panels through the sides and sleeves, eliminating flapping fabric and sealing out cold air. It's the kind of jacket you'll wear for the entire ride in mild conditions. And if the temperature rises, it packs away easily into its own side pocket to disappear into your jersey pocket or seat bag.

Classic, evolved. Performance, enhanced.
