I prefer a small duffel that is essentially a large waterproof stuff sack. It gives me more space than I need, so when I leave the grocery store I have the volume that I needed to hold everything that I bought. Fully loaded without food my duffel is only about 20 percent full but it is great to have expandable space for when you need it for more food or water bottles.
