I recently found the hollofil mummy bag I used in my teens, about 30 years ago. At the time it was quite a warm bag, only usable when it was very cold out. It's been stored "randomly stuffed" into a stuff sack for all that time, in another bag in a garage (so protected from dirt, direct moisture, and the worst of temperature extremes).

There are answers for restoring a down sleeping bag and advice on restoring loft to synthetic and down bags stored for shorter periods, but is it feasible to restore the loft on this bag?

One thing worth a try is if you have a tumble drier (clothes drier) that will do cold or at least cool. The last 10-20 minutes on the timer is often cold.
