Castelli Women's Espresso Air Jacket The Castelli Women's Espresso Air Jacket is made for cold and mostly dry days, delivering impressive warmth and breathability as you build your winter base. With Ristretto Warm fabric, you get the benefits of a warm and fleecy inside paired with just enough airflow to prevent you from overheating or getting soaked in sweat.  Ristretto Technology A new clothing technology for creating warmth when cycling in winter while keeping you sweat-free. Ristretto fabrics let through an imperceptible amount of air, so you won't even notice it. But this air permeability allows jerseys and jackets to breathe far better than traditional membrane cycling tops. The Espresso Air also gets a cosy fleece inner face, enabling you to take on colder temperatures and cope with varying degrees of effort while remaining perfectly warm.  Fit for Winter The Espresso Air Jacket offers plenty of stretch, letting you enjoy a streamlined fit, just what's needed for conserving winter watts when building your fitness base. Castelli has also applied a PFAS-free DWR (Durable Water Repellent) finish, fending off passing rain showers and damp roads. Double-layer cuffs keep warmth in and integrate with winter gloves too. The front zipper is two-way, letting you open from top or bottom, making it simple to regulate your body temperature.  Three back pockets provide plentiful storage. To keep the contents secure, Castelli has added a security lip to the top of the pockets. A reflective stripe under the pockets gives added visibility on darker winter mornings and evening rides.
