Made for cool days, the Perfetto Air Vest is constructed from Castelli's own Ristretto Lite fabric, which allows a restricted amount of air in, just enough to evaporate sweat so you stay dry and warm but not enough to become chilly. It offers mild insulation and rain protection too.Enhanced with a DWR treatment that causes drizzle and spray to bead up and roll off, the vest features a stretch-woven back for a tailored fit and excellent breathability, while a top-and-bottom opening zip gives you on-the-fly venting options.Benefitting from the membrane and lamination experience of ITTTAI®, co-designers of the Ristretto technology, the vest includes three rear pockets, with a security lip to keep your essentials safe and reflective piping to enhance your low light visibility. All of this adds up to a versatile vest that's perfect for hinge season rides in mainly dry but changeable weather.Key Features:A mid-weight vest for protection in cool temperatures and on wet roadsMade from Castelli's exclusive Ristretto Lite fabric, created in partnership with ITTTAI®Fabric is enhanced with a DWR treatment and exhibits breathability, warmth and stretchBack of vest is stretch woven for even more breathability, front and back are windproofWith top and bottom opening zipper3 x rear pockets with security lip and reflective pipingPFAS freeMade for temperatures of 10-18°C
