I have a used MLD Prophet w/the suspension upgrade size Large for sale.  The suspension ads lift loaders and a Klymit inflatable back pad for support/rigidity.  The pack has seen about 1.5 years of use and has some signs of wear, mainly on the side water bottle pockets (holes in the mesh) and the bottom of the bag (some abrasion and very small hole or two).  Asking $150 shipped.
