We just purchase our third rolling backpack , just because my daughter wants a new design for middle school.
The last school year we had the purple one, that went through a lot of stair, going up and down, caring a lot of heavy books, and at the end survived in perfectly conditions, just a small hole on the side pocket, very study and spacious backpack, highly recommended, and all their designs are super cute for boys or girls , our first one was the Paris design, absolutely gorgeous.
The new one they changed the material on the side pockets, hope will be sturdy, as the old models., besides that For my family Tilami brand Have the best backpacks
