Teef: when I had an ALICE pack, although amazingly capable, I never found that frame too comfortable...
sadly i have to concur. my issue with the ALICE packs is the damn mounts for the hip belt. why do they have to come straight off the frame at 90 degrees? who has 90 degree shaped hips? sure as hell not me and those mounts end up killing me after a few hours. i've tried extra padding, cinching up the belt mounting straps, etc but none of it has actually solved the problem.
i've seen on U-tube where guys take a ballpeen hammer and bash the mounts to splay them out as much as they can but that seems like a hell of a bodge to me and only a fraction of a proper solution to the problem. not for me.
what i have found is that there is a NATO version of the ALICE frame -- it accepts ALICE bags without a hitch -- that solves exactly that problem: the belt mounts are splayed way out so there'll be no hip gouging no matter how you wear the thing. sturdy little frames too, but of course there's a catch: stripped bare the thing weighs almost 4 kilos!
