I got this backpack for my 8 year old son for school. I had bought a different K Cliffs backpack for my other son earlier and was pleased with the quality of the bag for the price. This bag, however was not of good quality. Within a week, the zipper was broken. After 1 month of use, you can see through the bottom of the bag and there is a small hole in it! VERY DISAPPOINTED!
