Castelli unveils Perfetto RoS 3 for the PFAS-free era
Castelli has released the latest version of its autumn, winter, spring Perfetto jacket, the Perfetto RoS 3, featuring a new membrane fabric developed with Polartec. Called AirCore, the material is made from recycled polyester and represents Castelli's new approach to balancing breathability with weather protection, following the industry-wide shift away from PFAS-based waterproofing.
According to Castelli, AirCore delivers a small but measurable level of air permeability (0.7 CFM) to aid breathability and moisture management, combined with a waterproof rating of 5,000 mm. That figure is lower than the 10,000 mm benchmark often used in the outdoor industry, but Castelli argues cyclists rarely need that level of waterproofing and would be better served by improved breathability. The new fabric is also approximately 25% lighter than its predecessor, meaning the Perfetto RoS 3 may feel cooler than the outgoing model, with Castelli suggesting a comfort range of 4–14°C, depending on the chosen base layer.
The jacket retains some familiar Perfetto features, including reflective stripes, drain holes on the three rear pockets, a high collar, taped shoulders, side vents, and a two-way zip. Early riding impressions suggest that the 14 °C upper end of the temperature range is a bit optimistic, but the jacket is suitably water-resistant for passing, even heavy, rain showers and dries exceptionally quickly. A full review will follow shortly.
The Perfetto RoS 3 is available now in men’s and women’s versions, priced at €250 / £280 / US$320.
