How to clean a sleeping bag?

The composition label of the sleeping bag is important: the washing temperature will vary according to its fabric(s). If your sleeping bag is made of hypoallergenic wool or organic cotton, you can machine wash it at 30°C, using a wool program with a special detergent for wool. If your sleeping bag is made of another material, you can wash it at 40°C, but always refer to its composition label.
