Washing a Patagonia Down Jacket: Cool Water and Low-Heat Drying
Patagonia advises washing down garments in cool water with mild detergent in a front-loading washer, then tumble-drying with clean tennis balls on no or low heat. Always check the garment label first.
Down can lose its loft if drying is incomplete. Patagonia's official support note says tumble drying may require multiple cycles. This guide covers Patagonia down garments; do not assume the same procedure is safe for every brand, coating or garment.
