I store my sleeping bag stuffed loosely in a large pack. I do not store it packed tight in its carry bag. There’s a good reason why.
I’ve just been camping in Waikawau DOC Park. After this camping trip, I air dried my bag for a few days before storing.
I never store my bag in its small stuff sack. The longer I compress the insulation, the more loft it loses. It’s fine to use a stuff sack-even a compression stuff sack-on while I am evacuating or moving away from a disaster area , but the minute I get home, or set up camp, I get my sleeper out of that confined space, give it a good shake to fluff up the fill material, then store it in a cool, dry place.
Spread it out under your bed, hang it in a closet, or put it in a big, breathable storage bag (often provided by the manufacturer). If you don’t have such a sack, use a king-size pillowcase. 1
