Castelli Beta RoS Jacket

This thin wind and splash protection offers surprisingly much warmth while being so light and stretchy that you hardly notice it. Race-fit for performance on fast autumn and spring rides in any terrain. As summer transitions into autumn, we still have a few months to enjoy wonderful rides, but as we start to dress warmer, we miss the freedom of just wearing a jersey. That’s why we developed this jacket. We used the lightest and most flexible fabrics we have to create a jacket that blocks most of the wind, is highly breathable, provides remarkably high water protection, and essentially disappears so that you don’t really notice it. Since this is a performance jacket, we focused on the essential task. There’s nothing superfluous, unless you consider the large reflective panel on the back unnecessary. We don’t. We designed it to fit close to the body so that the fabric doesn’t flap in the wind, which also helps keep the jacket warmer. The pockets are generous and easily accessible, the zipper opens smoothly, and the logo is discreet.
