Revolutionary apparel for winter outings: with the Perfetto Air W Jacket, cold and humidity will be a thing of the past. To design this jacket, we created our new fabric with Ristretto technology. A technology that precisely regulates the amount of air that can pass through it, but also, and most importantly, the amount of moisture inside that can be transferred to the outside. Because if you are dry, you are also warm and will have a greater feeling of comfort. And if you feel warmer, drier, and in complete comfort, you will be able to go on longer bike rides. The fabric with Ristretto technology is not only breathable but also stretchy, for an unprecedented fit. The Perfetto Air W Jacket is made entirely of Ristretto Lite fabric, to offer you maximum breathability and comfort. The elastic component of the fabric allows for a close fit that provides total freedom of movement. Furthermore, being a winter jacket, we equipped it with insulated zones, to keep you warm right where the cold air would be felt the most. This jacket is ideal with a short-sleeved baselayer on cool days and our Flanders baselayer on cold days, giving you a wide range of temperatures in which to wear your Perfetto Air W Jacket. You won't have to worry if you get caught by a passing rain shower or wet roads, because the Ristretto Lite fabric keeps water out thanks to the long-lasting PFAS-free DWR (Durable Water Repellent) coating. For those days when you know it will be raining or be humid, this jacket is the ideal match to pair with the Ultra Rain Cape for complete protection and a close fit.
