The school bags mainly designed to hold large numbers of heavy textbooks and note books and hence their designs are simple with few straps and backs. The reflective panels, which makes the wearer visible at night is one safety feature given in these bags. The ergonomic features are also considered while designing these bags and hence padded straps and waist straps are given so that the weight is distributed all over the body. Some school bags also have special designs to carry certain high value items such as laptops or cameras.
