Great sturdy perfect size for my little 5 yr old boy whos goes to pre K 3 days a week and on those school days must bring, to & fro, his blanky, his lunch box, extra clothes & shoes. THeres even a place for his water bottle which leaks if its not standing upright so the side mesh holds the bottle in place and makes a great addition to this "for kids" school/luggage bag. Everything fits which makes leaving home and then leaving school so much easier regarding packing up everything which use to take alot more of my effort and time. My boy even likes to wheel it himself which is a nice change for the better. Highly recommended.
