Backpacks are an almost daily necessity from the time you dry your tears at the doors of your first preschool class, to the day you walk out of college with that newly-minted degree. And the best backpacks will last long after that as well.

ConsumerSearch has evaluated expert and owner reviews to find the best backpacks for any age.
