let us know, don't hear much about IA packs... the only really in depth review i have seen was from someone's opinion i trust very little (not on this forum)
i hear you on prices getting high, but packs are one of those zero compromise pieces of gear... it's important it suits you well. i hope the IA fits that criteria for you. i am pretty settled in on packs right now, but IA is still interesting to me.... i'm more of a "don't care if it's the comfiest pack light (they are all pretty good in that regard) but want it to make a really heavy load stick to my body, and feel stable, and not be annoying wearing it a bunch of days in a row with 35ish lbs in it"
i have tried every pack system i was curious about, and packed heavy loads of meat several miles at a minimum for all of them, gave them all a very fair chance, even after the first rough pack out for those that didn't work, which has also made it very clear how much better a couple fit me vs the rest.... i do want to revisit Seek Outside, because i love their stuff and am not convinced that my issue with it was user error (entertaining the idea at least) because they are so adjustable, maybe i never landed on the right adjustment for my body.... they have a lot going for them for some of the hunting i do, and everything i have got from them has been great quality and well thought out (like kifaru and EXO)
hopefully at some point, USA made will not carry such a huge added cost by default, but for now, it is what it is
