looking at those ridge rest mats in another tab, those look pretty nice, and not as expensive as I thought they might be.

When you attach a sleeping bag to the outside of your pack, is it a good idea to put it in a compression sack first? I tried attaching one without it, and it was awkward and uncomfortable, and the sleeping bag kept sliding apart and coming unrolled. I am assuming a compression sack or some other stuff sack would solve this problem.
