Sven, hmmm of course, depending on your gear and everything, i do believe you could get 7 days out of this pack without to much problem, i carried 7 days when i started with a 30 degree bag, solo poncho tarp/bivy, torsolite, minimal clothes, solo pot etc. and fit it all in (though tightly) so in the summer, if you got a low volume kit, you might be able to get 10 days in.
Michael, ya your correct, i mean i'd say with any frameless pack, over 25 pounds your pushing it. and the only times i'd push it would be for a dry camp, or carrying stupid stuff out of towns, and i didn't worry about things ripping off. personally my average load was in the high teens and i'd forget i'd have the backpack on.
