DOWN
USE A MILD WOOL DETERGENT.
Wash your down jacket or coat on a gentle cycle at 30 degrees °C with a mild wool detergent. Avoid using softener.
TUMBLE DRY ON LOW HEAT.
Use the lowest heat drying setting possible and add dryer balls (or tennis balls) to help maintain the volume and insulation properties of the down.
REFRESH AFTER STORAGE.
If you have stored your down jacket over the summer, refresh it for the new season in the tumble dryer, using a low-heat setting. Add dryer balls (or tennis balls) to help fluff up the jacket as it dries and prevent the feathers from clumping together.
