Castelli Perfetto RoS 3 W Jacket 2026

The Perfetto RoS 3 W Jacket is the ultimate versatile jacket for demanding cyclists, combining protection, breathability and comfort. Designed to tackle most conditions, it is windproof, highly water-resistant and stretchy, whilst offering the best breathability on the market thanks to its exclusive Polartec® AirCore™ 150 g membrane, which is breathable and PFAS-free.

This jacket is ideal for cool days and can be layered with an extra thermal layer to tackle the cold. The reflective taped seams on the shoulders, the two-way YKK® Vislon® zip and the zipped ventilation openings on the chest ensure comfort and protection, whilst the three rear pockets with drainage holes and reflective piping provide practicality and safety.

Its slim-fit yet stretchy cut hugs the body perfectly without constricting it, with an extended back to protect against splashes. Lightweight, breathable and high-performance, this model represents a major step forward from the famous Perfetto Gabba, offering a premium jacket capable of handling wind, rain and intense exertion with exceptional control. The Perfetto RoS 3 W Jacket is the jacket that combines elegance, technology and versatility for all outings, even when an unexpected downpour strikes.
