The Aria Shell Jacket has always been among the most functional in our line. Now it is even more so. We have refined the fit for greater ergonomics and added reflective details with our new logo and logotype, to make you even more visible, but always with style. It is incredibly light, windproof where needed, but breathable thanks to the side mesh panels. But now the fit is even closer, thanks to the new elasticated side and sleeve panels: the fabric doesn't flap and cold air stays outside. It's the type of jacket you'll wear throughout your ride in mild temperatures. And if the temperature rises, you can easily fold it into its side pocket and stow it away until it disappears into your jersey pocket or saddlebag.

Classic but evolved. For even better performance.
