The Castelli Perfetto Air Vest is engineered to be the ideal outer layer for cool-weather rides, offering warmth, breathability, and versatility in a lightweight package. At just 173 g, it delivers moderate insulation through Castelli’s exclusive Ristretto fabric technology, developed in partnership with ITTTAI®. This innovative fabric uses engineered air permeability to remain mostly windproof while allowing controlled airflow that carries away excess moisture, keeping your core dry and comfortable. The front features mid-weight Ristretto Lite fabric with a PFAS-free DWR treatment for added water protection, while the stretch-woven back enhances both fit and breathability. The tailored cut ensures a streamlined profile on the bike, and the high collar provides added warmth, often eliminating the need for a neck warmer. Designed for 10°C to 18°C (50°F to 64°F), this vest covers a wide range of conditions without bulk.

Practical features make the Perfetto Air Vest a rider’s go-to for transitional weather. A double-opening YKK® Vislon® zipper allows precise ventilation control, whether you need to shed heat on climbs or lock in warmth on descents. Three lie-flat rear pockets with security lips offer generous storage while keeping items stable, and reflective piping at the bottom of the pockets enhances visibility in low-light conditions. Combining advanced material innovation with a sleek, functional design, the Perfetto Air Vest delivers premium performance for riders who demand warmth, dryness, and adaptability without compromise.
