Just stuff it in the bottom of your pack and pack other gear on top. It fits better than putting it in a stuff sack and putting that cylinder into a pack.

Are you looking for a compression sack or a storage sack?

I have a pretty similar bag. A 15 degree Kelty down bag. I think it’s the long version not the regular. I use a 9L sea to summit ultra sil stuff sack. It fits just about perfect.
