Stay Warm and Comfortable with the Jacket Designed for Professionals

As summer turns to autumn cyclists still have a few months of amazing riding, but when the weather gets colder you miss the freedom of wearing just a jersey. That's why Castelli created the Beta RoS Jacket, with unbelievable comfort designed just for women.

Built with Polartec® NeoShell® fabric that provides an incredible 4-way-stretch, perfect for protection from wind and water on the front and upper sleeves. The back of this cycling jacket flaunts highly breathable Nano Flex Light woven fabric for an ultra-comfortable ride. Designed with close-to-body cuts that, combined with the 4-way stretch fabric, delivers a streamlined fit that isn't too tight on the body. Featuring a durable YKK® Vislon® zipper that slides easily for quick ventilation control, allowing for the perfect temperature in a flash.

Cycling during the changing seasons can be a tightrope balance between too hot or too cold, but with the Castelli Wome's Beta RoS Jacket you can warm up or cool off with ease. Embrace the chilly months with open arms — and fall in love with the feeling of a satisfying cold-weather ride.


  • Polartec® NeoShell® 4-way-stretch fabric on front and upper sleeves is windproof, waterproof and highly breathable
  • Nano Flex Light woven fabric on back is highly breathable while blocking wind and splashes from light rain or wet roads
  • Close-to-body cut remains very comfortable thanks to 4-way stretch of all fabrics
  • YKK® Vislon® zipper is easy sliding for quick ventilation control
  • 3 rear pockets
  • Large reflective panel at lower back
  • Temperature range: 8°C - 18°C (46°F - 64°F)

    Castelli jacket sizing is off

    I should have learned from dealing with this issue with Men's shorts but Castelli sizing is inconsistent. Tends to run small. I ordered this jacket and a base shirt for my wife, both in size Medium. The base shirt fits but the jacket doesn't come close to fitting! The jacket itself is nice so I'm exchanging for a size Large. Too bad I need to pay the return fee on top of an already pricey jacket.

    Love wearing my Beta RoS Jacket in the Cold Winter Weather flashing the awesome hues of Brilliant Pink and Dark Grey on my group rides.

    I ride four to five days a week even in the Winter. I wear my Beta RoS Jacket in 35-40 degree weather and it really keeps me warm. I like the slim form fit and soft feel of the jacket. If I need to remove the jacket, it can be rolled up easily and placed in my back pocket. The quality is exceptional and I also love the color of Brilliant Pink that matches my Castelli pants, gloves and helmet.
