My 5 year old loves this. It's the perfect height and although it doesn't expand because it's not hard shell we were able to squeeze his large CAR pillow inside with clothes for 5 days, toiletries and 1 pair of shoes. The cooler pockets are on both the backpack and luggage but we used it forwet/ dirty clothes. The backpack had just enough pockets to organize his tablet, Chargers and headphones. We've checked it once and it's held up so far. Very pleased with this purchase.
