Beta RoS Women's Jacket

The Beta is a thin wind and splash barrier that provides a surprising amount of warmth, while being incredibly lightweight. At 185g the Beta is lighter than many long sleeve jerseys. In fact, it is so light that you will likely not even notice it, yet you will still have the protection promised by many jackets.

The jacket achieves the triple crown of wind and rain protection, breathability and low weight by using a combination of Castelli’s lightest and stretchiest fabrics, Polartec® Neoshell® and Nano Flex Light.

Polartec® is used on the front and the upper of the sleeves to provide windproof and waterproof protection where you need it most. Nano Flex Light woven fabric is used on the back, allowing any excessive moisture and heat to escape whilst also shedding light rain.

The Beta RoS Women’s Jacket is a performance piece, with nothing superfluous on it. A YKK® Vislon® zipper provides easy opening and closing, even when the pace is high, and 3 rear pockets are just the right size and easily reachable. The only thing that could be deemed superfluous is the large reflective panel, but on cool, grey evenings added visibility is always worthwhile.

The race fit achieved through the high stretch fabrics and close cut minimises flapping and is reflective of the kind of high intensity, fast riding you will be doing.

Ride unhindered and focused on your efforts, whatever the weather decides to do.
