The Ivar Shelf System design was created by Ian Ivarson. He designed it to evenly distribute the weight of the contents by stacking them vertically, which reduces the torque load. This design makes the backpack ergonomically correct, which protects the back and spine, and add additional comfort when carrying it from place to place. The shelves also help with organization of your contents for school and recreation, as opposed to the typical design, where its one main compartment for your stuff. These backpacks are made to last and will benefit those individuals who have current back problems.
