Yea, clearly you also need bags for the lens, batteries, and so on. What exactly you want to use is your choice, I actually mostly use food plastic bags, neoprene bags, and water and air-tight roll-up nylon reinforced woven bags meant to swim on water. Also for clothes, because I don't completely trust muh backpack from experience.
