Classic charm meets modern performance.
A fresh take on the heritage newsgirl silhouette, the Harper brown cap is crafted from 100% wool and designed to keep you dry in style. Its fuller, panelled crown and structured peak create a flattering, softly tailored look, while a breathable Porelle membrane ensures it remains fully waterproof without compromising on comfort. Whether you're heading out for a weekend walk or navigating the city, Harper delivers effortless elegance, whatever the weather.
