The interior has many compartments for organizing items, making it convenient to store notebooks, pens, water bottles, tablets, and more. There's also an anti-theft pocket on the back, so you can safely store valuables such as your wallet and smartphone. Even if your battery drains incredibly fast, it's no problem!
