Only thing I sometimes don't like about mine is when it's very stuffed with gear and water, I can sometimes have problems with it creeking/squawking where the bag slips on top of the carbon-fiber frame pieces up top. They will bend/flex and the outer-most edge will curl towards the back, and I think this causes that top sleeve of the bag which slips over the top of the frame tops to be able to rub against it sometimes.
I could not believe it... but upon contacting them about that issue, their suggestion was to put some hokcey grip tape on that top of the frame pieces before slipping them into that slip-over sleeve from the bag. The solution did temporarily handle the issue... until it works it's way back out again and falls off. But... for the money paid.. I was rather pissed that all they had to offer-up was a cheap-@$$ bubblegum type of solution for a product I paid a pretty penny for. To me that's just not right. There should be no way in hell a user can willfully be able to do something that would make your product make that noise. If it can... debug it!! Go back to the drawing board and address the design issue, and make a better iteration of your product.
Because of my sort of OCD ya might say, it really irks me when this creeking/squawking happens as I pride myself on being quiet and lifting my feet and picking the quietest lines thru the terrain, etc. And the area I'm thinking of you can hear something like that for quiet a ways in the quiet of first-lite.
Now... that having been said I'm VERY fond of how this pack is big enough to carry everything and the kitchen sink! It's purpose was to make sure I could packout meat in just 1 trip. And you can with this thing. Sometimes I elect to make it two-trips if my lower back injury issue is problematic at that time, but that's on me, not the pack. The pack can carry heavy weight quiet well if you don't have my injuries. And the shoulder straps were next level comfortable! Was such a nice step up in comfort at weight compared to the lesser quality and smaller used pack I'd used before.
