Yorepek Basketball Backpack Bag, Blue

If it is going to school

If the pack is going to school on a child, weigh it. The american academy of pediatrics puts the ceiling at 15% of the child's own body weight, asks that the bottom of the pack rest in the curve of the lower back and never sit more than four inches below the waistline, wants two broad padded straps rather than one, and says the heaviest things — the textbook, the laptop — ride closest to the back. A compartment count is not a substitute for any of that. Our capacity figures say what a bag holds, not what a person should carry.

Every figure in this note comes from a named public source. All of them, with the date we read them, are on our updates page.
