I am a Backpacking instructor for a college in Binghamton NY and recently tested a new product called RIBZ. This front pack system allows you to take 10 or so pounds of essential gear from your pack and put it in the front where it is easy to access. The pack also helps balance your weight. I have a bulged disk and this pack helped keep the pain at bay. Bushwacking was never easier and the pack is durable!! Try one for yourself. I loved them so much I became a rep and am selling them for less than the company who makes them so I can build my rating and customer base. Check it out.
