This is the Duluth pathfinder pack... do not know the liters. Measurements...22"H x 17 " W x 6 " D...this pack carries a lot of gear...I like this pack.....but I'm done. It is well made, it is bomb proof. It is heavy 3 lbs empty. It is uncomfortable with no frame or suspension. Can anyone recommend a pack of this size in capacity but is modern, lighter and has some suspension or shape. I think I remember a redwing or something similar...I think it may be connected with Alone... I think different sizes...not sure if this is even what I'm looking for.....hoping all you folks can help so I can narrow down a sesrch.
