I had a peregrine, and I wanted to like it, it was a killer pack, but was punishing with over 80#. I could not get it comfortable under load, I roughed it out through several pack outs but it wasn’t happening, tried the lumbar pad, no pad, and everything I could think of, and it was just not good for me
Most people seem to like them, I am likely an outlier. I liked the design and weight, and the peregrine was a very versatile bag for me, but I had a couple of my most painful pack outs with it
