You don't have to wash your DÄCKE after every use. The following applies: as often as necessary, as seldom as possible! The DWR coating is water-repellent. This means that even larger contaminants can be easily wiped off. If a wash is necessary, the best way to do it is as follows:  Wash  - Hand wash in a bathtub & only very heavily soiled in the washing machine (no top loader). - Select gentle program without spinning (0-30°). Then select Rinse & Spin again. - Absolutely avoid fabric softener. This can damage the composite of the artificial down.- Use a special detergent for down (1/3 is enough). dry - The DÄCKE dries best in the fresh air. - Do not hang to dry. This can cause the filling to shift. - It is best to lay it flat on the ground in the sun. - Turn & shake out more often. - Even if everything seems dry again, there may still be a little moisture inside. Better to let it dry for several hours. Store It is no problem at all to keep your DÄCKE in the stuff sack for several days. But please uncompressed, because extreme compression can impair the heat effect in the long run. But if you don't use them for a long time, you can store them in the largest pillowcase you have.
