With the right care, down-filled jackets will come up clean, fresh and looking like new after a wash. With the wrong treatment, they can end up smelling like a wet dog and looking a right mess.
Follow the washing instructions inside the coat (usually a gentle 30° cycle). Then hang the jacket to dry naturally in a warm, well-ventilated area away from direct heat. Once dry, put the coat in a tumble drier on a low setting, along with two tennis balls. This will re-distribute and ‘fluff-up’ the down/feather mix.
