My daughter used this backpack for three months at school, but she alternated with other backpacks, so I don't think it's been used much. Height: Approximately 49cm Width: Approximately 30cm Depth: Approximately 15cm There are three zippers, and each can hold a large amount, so the depth measurement is when the bag is empty. Water bottles can be stored on both sides. A practical black nylon backpack with mesh pockets. - Brand: New Balance - Color: Black - Material: Nylon - Design: With mesh pockets - Logo: Red logo Thank you for looking.
