Women's Beta Ros Jacket

Castelli 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 basically disappears so you don't really notice it.

There's nothing superfluous on it, unless you consider the big reflective panel on the back to be unnecessary. It has 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.
