Many puffer jackets can be tossed into the washing machine to be cleaned, but some can only be dry cleaned or require special care. Always check the care label of your jacket or coat to be certain. If you can machine wash your puffer jacket, Newberger suggests doing so before fluffing. "Try throwing your puffer into the washing machine at a normal setting, making sure not to reverse the sleeves, and keep the outside you want to be washed facing outward," she says. "After, re-fluff your jacket using the steps above."
