There are two zippers on this bag, so it gives you the option of having the zippers stored near the top of the bag or off to the side. This is a great helmet bag for the cheap price ; you get what you paid for. Even though the bag doesnt seem too durable itself, as long as it doesnt take too much contact it should last. The inside is a sort of white fluffy cotton style lining. However, if you want an extremely durable bag look somewhere else....
