Yes, any old stuff sack will do.

For what it's worth, I don't even use a stuff sack. I just stuff it into the biggest stuff sack I have: my pack. Doing this means it fills every nook and cranny of the bottom of the pack, and makes packing other stuff easier. It also allows me to adjust the volume of the sleeping bag so the rest of the gear fills the pack better. (I stuff it more loosely as I eat up the food during a trip.)
