After outdoor camping, when packing the sleeping bag, you can first roll it up once to squeeze out most of the air. Then spread the sleeping bag out and irregularly stuff it into the compression sack starting from the tail end.

This method not only prevents the sleeping bag from being bulky when folded but also plays a certain role in maintaining down sleeping bags. It is not recommended to roll the sleeping bag regularly and then put it into the compression sack, because long-term regular rolling will cause the sleeping bag’s outer fabric to age faster due to uneven force.

However, if the weather is extremely humid during the trip, and the fabric of the down sleeping bag is waterproof or water-repellent, please seal the sleeping bag in a plastic bag to prevent humid air from entering. It is best to wrap the sleeping bag in a bag first, as this will make it less susceptible to environmental and climatic influences and avoid damaging its temperature rating.

Press the rolled-up down sleeping bag with both hands, then fasten the straps on the sleeping bag. In this way, a bulky down sleeping bag becomes a small bundle of "quilt" attached to our backpack. Only this folding method can save the maximum storage space. After all, when we are trekking outdoors, the less weight and volume of our outdoor gear, the better.

Additionally, a reminder: Untie the straps of your sleeping bag in a timely manner and store the sleeping bag in its natural state (hang it in a dark place or lay it flat in a storage bag). This allows the filling fibers of the sleeping bag to regain elasticity and maintain their proper loft, ensuring good warmth retention performance.
