More than just an evolution, it represents a true revolution, much like the Gabba did in its day.

Suitable for everyone with its perfectly fitted cut, this jacket features a new exclusive Polartec AirCore fabric and a PFAS-free membrane. More breathable and water-resistant, this jacket ensures excellent ventilation with its zipped chest vents and two-way zip. Thanks to all these features, this Castelli Perfetto RoS 3 Jacket will accompany you on all your cycling adventures, particularly in mid-season but also in winter when the weather isn’t too cold.
