Engineered for women who ride through anything, Castelli's Perfetto RoS ("Rain or Shine") Jacket delivers revolutionary protection from wind and rain in temps in the high 30's to 50's (or as a layer in colder weather). This is the jacket that does it all. This generation of the Perfetto uses Polartec® AirCore™ membrane, making it fully windproof and water-resistant defense with an industry-leading level of breathability. Strategic features like a top/bottom opening full zip and zippered side vents move heat while preventing the jacket from flapping. Three drainable rear pockets carry essentials, reflective details ensure visibility, and taped shoulder seams plus extended tail lock out rain - making this soft-shell jacket your go-to armor for cold weather. When the forecast is unpredictable but your ride isn't, perfection has a name - Perfetto ROS 3. Athletic fit.
