School rucksack, has narrower side walls, base and top side in order to distribute load more evenly

摘要

The side walls, base and top side of the rucksack are all narrower compared with a conventional school rucksack, reducing the rucksack volume. At least one additional bag can be attached to the front of the straps in order to be carried on the chest and balance the bag carried on the back. These bags can be attached to a vest instead of straps.
