The correct storage method for hollow cotton sleeping bag:
The hollow cotton sleeping bag is produced with the development of man-made fiber technology. In addition to keeping warm through the expanded fiber gap, the hollow fiber can also keep warm inside.
Therefore, it is better than down sleeping bags in that it can still have some warmth retention performance when wet, but its compressibility and weight are not as good as down materials, so it cannot fully replace down products.
Similar to down sleeping bags, most hollow cotton sleeping bags also adopt a three-dimensional structure, so two folding methods can also be used. Here we do not suggest to you which way is better, I believe you will gradually develop a fixed habit in use.
The correct storage method for ordinary cotton sleeping bag:
The compressibility of ordinary cotton sleeping bags is far worse than the above two sleeping bags, if you use the way of random stuffing, it may be more difficult. If you think about it, you will understand that random insertion will produce many gaps. Materials with good compressibility will fully fill these gaps, while materials with poor compressibility can only partially fill the gaps, resulting in greater volume. For ordinary cotton sleeping bags with poor compression properties, it is recommended that you roll them up and fold them up. Not only can you easily put the sleeping belt cover, but also save a certain amount of volume.
