Looking to get my 13 year old a backpack that will last him for all high school. Am thinking of the Brain bag with a Freudian slip - may be carrying a computer later on, and will be carrying text books for sure. Only concerns are that he is not very tall at this time (5' 1" maybe?) and loaded this bag may be too much weight for him (especially with his tendency to leave stuff in the bag forever instead of taking stuff out to file). The more organization a bag can provide the better for him I think. Any thoughts? Thanks so much.
