I’m 5’10” on a good day, my mountain shape was 212lbs this year. I have a 32” waste and a 44” chest. I own 3 mr packs, 2 are GL framed. My pack going in on my archery elk hunt was over 55lbs on the way in. Didn’t have any issues with the pack on the 5days back in. Besides the infamous noise, the only complaint I have is bending over to pick something up, the top of the frame cuts into the upper part of my neck, making something very simple more awkward than it needs to be. The only struggle I have while using a GL frame pack is the same with all packs, they seem cut into my traps, more so a me shape problem.
