Washing: Hand-wash your parka in cold or lukewarm water with a mild detergent. Avoid excessive rubbing to preserve the quality of the polyester.
Drying: Air-dry by laying flat or hanging in a shady spot. Avoid tumble-drying, as heat can damage polyester.
Ironing: Avoid ironing the polyester parka directly, as heat can damage the material. If necessary, iron at a low temperature, using a thin cloth to protect the fabric.
Storage: Store the parka in a clean, dry place. Avoid compressing it to preserve its shape and properties.
