As tempting as it may seem to store your wearable sleeping bag in its own stuff sack, it’s best not to do this. Keeping it stuffed in the stuff sack compresses the materials and the insulation. Prolonged compression of this insulation will affect how well it can plump up, or loft again. This can considerably decrease its insulation properties. The other thing you should avoid at all costs is to not air your warble sleeping bag out when you return home from your outdoor adventure. If the sleeping bag has even a miniscule amount of moisture or dampness in its folds, it can become a mold problem and ruin the entire sleeping bag.\r
