An ergonomic bookpack having an automatic suspension system is disclosed. A series of top straps, side straps (400), bottom straps (500) and optional support members serve to move the backpack center of gravity higher in the bookpack and closer to the wearer's body, significantly redistributing the load borne by the wearer's shoulders along a longer portion of the body and back. The body of the bookpack can be made so that the interior compartment of the bookpack body is transparent and the contents of the bookpack are visible to the human eye. The invention also comprises an optional yoke (340) and lumbar pad (700). This bookpack allows the wearer to bear heavier loads for a longer period of time with less fatigue, thus reducing the possibility of debilitating musculoskeletal difficulties <IMAGE>
