Send your boy off to class with the Dakine Grom 13L Backpack when school is in session. The main compartment has room for his books and folders, and a zippered front pocket helps him keep his pens and pencils organized. When school lets out for the summer, turn him loose at the skatepark for the day with his board strapped to the pack, a lunch inside, and his water bottle stashed in one of the side mesh pockets.
