— the backpack is usually carried on two shoulders, less often on one (however, this option is considered less suitable for children, because it does not distribute the weight so evenly). Unlike knapsacks (see related paragraph), knapsacks are usually padded; a rigid frame is provided only in certain models, and then rather to protect the contents and ensure the original appearance. As a consequence, backpacks are less "orthopedic"; they are quite suitable for high school and middle school students, but are not recommended for younger students. Of the general practical advantages of such models, it can be noted that when carrying, you do not need to take your hands; but you can get to the contents of the backpack only by removing it.
