My child used this purple back pack for almost 2 years. These days that doesn't happen! The only reason we decided to buy a new one is because the mesh sides where a drink goes got ripped a little. So we bought a pink version of this for 2nd grade. She is an average child and it fits her well even as a kindergartener when we started her with this. The price for these I never expected them to last for 2 years. Great product!!!!!
