1. After camping, it is best to spread out the sleeping bag several hours before sleeping, so that the down is fully inflated (if the camp is very wet, it can be taken out if the sleeping bag is not damp, and it can also be taken out when sleeping).
2. Bring down the left and right side of the sleeping bag, so that the feather is evenly distributed in the lining.
3. Then tap the sleeping bag from head to toe, with a light intensity, and make the down as evenly distributed as possible.
4. Then bring the sleeping bag to the collar, and open it to the inside of the sleeping bag.
5. This allows the air to fill the interior and lining of the sleeping bag so that the down has a larger expansion space.
Pack your sleeping bag and make it puffy in the tent.
