I bought this backpack for my sister because she didn't want a normal backpack for school. She looks absolutely ridiculous when she has it on because she has a petite frame but she loves it. To each their own, it serves its purpose I guess. She can fit all her heavy books, binders, and laptop while still having plenty of space. It has a lot of compartments and secret pouches, strong zippers, and nice padding. This is a well made heavy duty, sturdy, bullet-proof looking backpack. It looks and feels amazing so I definitely recommend it, plus the name itself would make you feel Ninja-ish.
