Query: 6th Grade Book Bag

My grandson chose this bag as he has another Jan's backpack that does not have wheels. As he had had it for some time, I agreed to purchase this one for him. He loves it. It carries all of his 6th grade books, papers, and school necessities as he changes classrooms. Some of his books are rather heavy. It has been just what he needed. It also addresses the medical concerns regarding the back problems now being encountered by young children who carry too much weight.
