This pack is a MYOG project to take a Jam 50 lt pack and add a GG alum frame while making the rest of the pack body with lighter materials. New condition. Finished wt 26 oz. The pack bag dimensions are exactly that of a Jam 50. Shoulder harness and hipbelt (with pockets) are from a Large Jam. I substitued a metal adjustable hook for the belt buckle. The front and sides are made with 1.9 oz UR coated ripstop. Extention collar is sinylon with a small zipper pocket and "over the top" closure. Right bottle pocket is Gridstop. Front Large pocket is stretch mesh. Left long side pocket is ripstop. Back panel and bottom are 140 Gridstop. Torso Length: 22" from shoulder straps to bottom of hipbelt. This is longer than a standard Jam- but it has been shown that the torso lengths on Jams are too short. The back is padded with contoured foam behind stretch mesh. You can take out the pad to sit on. $50 includes shipping in CONUS. Paypal please try to avoid their fees by sending it as a "gift". First PM to me, that pays, gets it. Thanks, Scott
