The Castelli Perfetto RoS 3 Jacket redefines all-weather versatility, delivering windproof protection, high water resistance, and unmatched breathability in a lightweight, tailored fit. Built from the exclusive 150 g Polartec® AirCore™ electrospun semi-air-permeable membrane, it sets a new benchmark for performance with a PFAS-free, environmentally conscious design. At just 244 grams, the RoS 3 provides a streamlined feel that is lighter and stretchier than its predecessor, allowing for a close-to-body fit without restriction. Zippered chest vents and a two-way YKK® Vislon® zipper enhance airflow and ventilation, making it adaptable to both mild rides and colder conditions when paired with insulation layers. Designed to withstand temperatures from 4°C to 14°C (39°F to 57°F), this jacket is ideal for unpredictable cool-weather rides where wind, showers, and effort levels constantly shift.
Practicality and performance converge with thoughtful details that elevate the RoS 3 beyond standard cycling outerwear. Reflective taped shoulder seams and piping beneath the rear pockets improve low-light visibility while reinforcing protection against rain. The longer tail shields from wheel spray, and three rear pockets with integrated drain holes provide secure, functional storage. With its balance of premium aesthetics, refined fit, and cutting-edge fabric technology, the Perfetto RoS 3 is more revolutionary than evolutionary—an essential piece for riders who want one jacket that truly does it all.
