Multiple Pocket Design, With this bag, you have more different compartments.
Starting from the front, you have a pouch-like compartment with two buckles that magnetically connect to keep it shut. Next, we have a small zipper compartment right above the pouch. It's a moderately deep pocket and can store a good amount of smaller items.
Moving on, we have 2 standard backpack compartments. On one side it has two open pockets, one smaller than the other, and these can fit small things like Altoids and whatever. On the opposite side, you have a zipper pocket, that its big enough to hold a lot of equally small items. Lastly, the compartment closest to the back of the bag is your laptop compartment. It has a stretchy pouch thing specifically designed for a laptop or tablet. it's definitely big enough to fit a 15".
