Washing: Hand-wash your down jacket in a large tub or bath with cold or lukewarm water and a mild detergent specially formulated for delicate garments. Rub gently to remove dirt, especially in the dirtiest areas.
Rinse: Rinse the down jacket thoroughly several times to ensure that all soap is removed.
Squeezing: Avoid wringing or squeezing the comforter to remove excess water, as this can damage the padding. Instead, squeeze gently to remove excess water.
Drying: Dry the down jacket flat on a clean surface, avoiding exposure to direct sunlight or intense heat, as this may damage the polyamide.
Repositioning the padding: After drying, gently pat the down jacket to redistribute the padding and restore its loft.
Ironing: Avoid ironing polyamide down jackets directly, as heat can damage the material. Most down jackets do not need to be ironed, but if necessary, iron at a low temperature, using a thin cloth as protection.
Storage: Store your down jacket in a clean, dry place. You can also store it in a breathable storage bag to keep out dust and insects.
