Backpacks with flap closures are a type of backpack that have easy-to-use zippers on them that usually close over the top of the bag. Flap closures are unique in that they tend to look like a book cover, and they can be opened on two sides.
This style of backpack is so named because the flap covers the opening. The flap typically has a top fastened by one or more straps and/or clips; these may be hidden underneath the flap or sit on top.
