I went on a 3 mile hike with 82# in my pack. 82# sucks sweaty donkey balls after the first mile or so. Called Aron with some fitting issues and he to me to shorten my straps. So I pull my belt off to do this and seems the bottom of my frame is buckling under weight. It also seems to lean to that side a bit. Is this normal? Hate to bother Aron again if I don't need to.
