- At 30°C on a delicate cycle with a product for down or synthetic fill (Nikwax Down Wash or Tech Wash) – depending on how dirty the bag is (rule of thumb: wash after about 20 overnights).
- Only partially spin dry!
- Never use fabric softener!
- For bags that weigh more than 1500 grams, check to make sure that the washing machine is large enough.
In a dryer: Best dried at low temperatures around 30°C, along with two to three tennis balls that help to unclump the insulation and restore its loft. Dry the bag thoroughly and hang up to air out at least a day or two before storing it away.
Without a dryer: Best dried in direct sunlight on a washstand. Turn the sleeping bag often and shake it out to restore its loft. Repeat the procedure until the sleeping bag is completely dry.
