The backpack for school needs to carry large notebooks, a pencil case, and sometimes a laptop, every day of the year. Eastpak rules the playground with its Day Pak'r, Back To Work, and laptop compartment models; Herschel offers its City, Retreat, and Little America in twill; Sandqvist has its rolled closure bags Grid and Stream; adidas has sporty models.
For middle school, a bag of about 24 litres, with a front pocket and a compartment that can hold an A4 binder, is enough; for high school and university, a padded space for the laptop becomes useful. Wide and adjustable straps distribute the weight across the shoulders. The entire back-to-school selection is in the Back to School.
