I have carried haul bags around, and everytime after the trip I have been so uncomfortable I swore I would just buy a cheap pack & let it be torn to shreds & throw it out after 1 trip rather than go through the discomfort of carrying the haul bag. My partner did not hate it as much as I did, but he was a 5'10" male with a pretty muscular build, and I am a 5'6" female that felt like I was carrying way too much. They hold up great, but are an ergonimic nightmare to carry. I use an Arcteryx roll top bag - not perfect but it is pretty comfortable for my size.
