Why do backpacks have roll tops?

A roll-top backpack is a type of backpack that has a roll closure at the top instead of a standard zipper. The top of the backpack folds over itself several times and then buckles or clips to seal closed. This style of closure provides a water-resistant seal and allows the backpack to expand to accommodate more items.
