Since I haven't used the bag yet, I don't know how waterproof it will be, but the roll top is big enough so that it will take 4 or 5 rolls before you can secure it to the buckles. That should be enough. It seems to be made well and the material seems thick enough to stand up to regular travel use. Since the roll top is so long it does make is a bit difficult to get things into and out of the bag.
