I am having a heck of a time finding a backpack that fits right. I have an Osprey Kestrel 58 I bought at the end of last year in preps for some backpacking this summer. I love this pack, except the shoulder straps do not fit right plus rub my neck, and the hip belt is probably too short but would be okay. Shoulder straps are not curving around my shoulders, just pulling back on my collarbone. Hip belt is not removable, harness is. I brought home an Ariel and an Aura. The Ariel really pulls away from my back when fully loaded, but the harness is great. I took it out and put it on the Kestrel, thought I had a solution until realizing the load lifter straps on the Ariel harness are too wide for the Kestrel's buckles. The Aura doesn't fit right at all. I tried the Viva and it was fairly comfortable but very hot against the back (no mesh). I tried a Deueter, didn't fit right at all. I'd really like to try a Gregory Deva 60 and having trouble finding one in my area. I know they are heavier but if it fits right I am good with that.
I think it's my shape that is the problem: I am pear shaped--small rounded shoulders, hippy, torso measures 19". I'm 5'9, 165 lbs.
Anyone have similar issues, suggestions, ideas? I'm getting pretty frustrated.
