Do you have a synthetic sleeping bag? Or a goose down one? Mummy shaped or rectangular? 40 degree rating or 0 degree?

All of these factor in to what size compression stuff sack you’ll need for your sleeping bag.

It can be overwhelming to parse down the different factors and decide which size is right for your bag.

In order to simplify things, I answered this reader’s great question on this topic, I’m hoping that it will help everyone figure out what size stuff sack to get for your sleeping bag! 🙂
