A few more recent innovations in packs... Aarn "bodypacks" use front bags to counterbalance the load on the back: https://www.aarnpacks.com/ https://www.aarnpacks.com/ NeoTrekk (formerly LuxuryLite) also offers a "front pack" for counterbalance that can be used with their pack. However, that is just one of the pack's many innovations, which include modular waterproof storage, quick-detach hip belt, camp chair conversion, attachable wheels, and more: http://www.neotrekk.com/index.html#stackpack http://www.neotrekk.com/index.html#stackpack The McHale Bypass Harness on McHale packs completely solves the inherent adjustment problems of the traditional load-lifter design used on most trekking packs. This innovation is not recent; its US patent has expired. Despite this, I do not know of any companies that have adopted it: http://www.mchalepacks.com/sarc/04.htm http://www.mchalepacks.com/sarc/04.htm
