Always follow the washing instructions written on the style’s care label.
Down jackets and parkas can often benefit from a soft outerwear cycle in your washing machine, but only at very low temperatures.
Never use fabric softener, and only use a very small amount of mild soap.
Make sure to be patient when tumble drying. Down jackets must always be tumble dried at a low temperature, even if it might take several cycles to dry your coat.
Throw in a tennis ball with the final cycle to make sure the down does not gather in clusters inside your outerwear.
