FS Blue Mystery Ranch Trance XXX model, 69l, 4200 cu in back pack.  Weighs 4lb 2 oz and has an X frame.  I used it as a day pack in elk season and hauled out parts of elk in plastics sacks twice with it.  Very nice pack when you have to carry lots of weight, but not too heavy for lighter loads.  The shoulder yoke adjusts with velcro, and it currently has a size small hip belt (very cushy padding!), and it is possible to order different sizes of hip belts from Mystery Ranch in Bozeman, MT.  It looks like new except where there is a little elk blood. I didnt try to wash it off but it may come off.

$275 plus shipping. Email .  2012 is when I got this pack.
