Keep an eye on this adidas backpack. It's made from a technical fabric that's highly resistant to wear and tear for a totally revamped style. The zippered compartment has plenty of room for you to organize all your belongings. Keep your phone and wallet in the zippered front pocket and your water bottle in one of the side pockets without zipper.
