I cant believe that horror story about stone glacier packs, in fact Im just going to call bullshit on it unless it was one of their very early prototypes. Ive had 100+ lbs in my SG pack and it was excellent. I also have a kifaru thats very nice but it is big, heavy and overbuilt.

Kifaru makes great stuff and the advantages are that its durable and you can basically set up the pack any way you want (pockets, bottle holders etc) but all that comes at the price of weight.
