A school bag is a bag, often with a strap. The strap is often worn so that it diagonally crosses the body, with the bag hanging on the opposite hip, rather than hanging directly down from the shoulder. They are traditionally used for carrying books.
The back of a school bag extends to form a flap that folds over to cover the top and fastens in the front. Unlike a briefcase, a satchel is soft-sided.
