Stuff sacks vary from bag to bag, depending on the size and shape of the sleeping bag, as well as on the fill. Sleeping bags filled with down are more compressible than synthetic filled ones, and need lesser volume stuff sacks. You can use a regular dry sack for a down sleeping bag, except for winter weather sleeping bags where a more complex compression sack is needed to reduce volume that the sleeping bag takes up in your backpack.
