1/ How to fold your sleeping bag
No need to learn origami!
TRUE OR FALSE? Always fold your sleeping bag following a specific folding pattern to ensure that it fits into its cover.
WRONG! This misconception can damage your duvet as it will always be folded in the same places. The feathers and wadding will pack down more easily and lose their insulating power.
For the purpose of preserving the sleeping bag and saving time, the best way to store it is to "stuff" it into its bag.
