I have a duplex frame with an amr bag. Pack seemed ok to me until I put about 60 pounds in it. I have a lot of space between the shoulder straps and my shoulders. After a 4 mile hike the muscles on the side of my hips were really sore. Also the bottom of the bag hits my butt and I can't seem to stand up straight. Is that normal? Should I shorten the frame up? I have no idea how these should fit, this is my first big pack.
