Castelli has released three new winter cycling jackets featuring Polartec AirCore technology, including the Perfetto 4, Perfetto Pro, and Gabba Pro. The brand expanded its lineup to offer specific thermal options for varied cold-weather conditions.
Why it matters
The release addresses cyclist demand for increased insulation through specialized fabric weights while maintaining sustainability with PFAS-free materials. The move scales the proprietary use of AirCore technology following its initial debut in previous seasons.
The Perfetto 4 utilizes a 219g AirCore fabric for higher thermal retention, while the Perfetto Pro and Gabba Pro feature a lighter 150g version. Pricing for the new range is set at $330 for the Perfetto 4, $350 for the Perfetto Pro, and $320 for the Gabba Pro.
