Love Jansport but smaller than I thought it would be.

I bought Jansport because my daughter has one and it is high quality and has lasted for 4 school years already. So I got this one for my other daughter who seems to go through one a year - I told her Jansport this year. Well we ordered this and it is too small for middle or high school. It's more for elementary kids size wise. It's too much trouble to return so I will hang on to it in hopes of being able to use it somehow.
