I'm no salesman, and i haven't done kokoda, but i strongly reccomend everyone thinking of doing the trek has a look at Aarn Bodypacks. I'm a rock climber/bushwalker/survival camper/ kayaker and these packs are the greatest! Without the full sales pitch, they basically allow full body movement (including a full extension of the arm and an effortless walking style) and balance your load across you body centrally. they incorporate drysacks and are really a perfect system. find below the link to their website, as well as a list of stockists in Australia. Cheers guys, I look forward to trekking the Mighty Kokoda sometime soon
