Swedish firm coXa carry AB has developed a new integrated front suspension design that integrates the shoulder and waist straps into a single buckle hub. Growing up, inventor Claes Bergkvist was a Scout and took his backpacking seriously. As he grew up, he came upon this concept. After working with several international firms to develop the design (including Duraflex) he was granted a patent last year.
In addition to introducing a line of packs, they are also looking for licensees of this technology. Above and below you can see different design concepts for this ergonomic backpack carrying system. One distinct advantage is that it frees your arms up quite bit as well as the waist which may well transfer to increased mobility.
