For those days when you want to feel a bit more polished while keeping the chill away, a smart lightweight jacket is a go-to in the summer-to-autumn months. Cefinn's utility-style Rory is cut from a machine-washable cotton twill that feels crisp to the touch and is crease-resistant. Ideal for plane journeys or overly air-conditioned offices, it has handy side pockets, a roomy silhouette, and the jacket collar folds down or up to a funnel neck.
