Max - sorry if I'm vague, probably because I don't know the pack market all that well.
I want the lightest 30-35L pack that rides well on my back.
Like I said before, I have an older Golite Jam that fits my criteria except I don't feel it rides very well.
do not want a frame, may not even use a CCF as a frame.
I like the pack to hug my back from top to bottom.
I carry most of the weight on my shoulders in this weight range, so minimal waste belt is ok.
tend not to like exterior mesh pockets, but not a deal breaker, I would cut it off.
in fact the fewer pockets the better.
I'm sort of looking for and extra large running pack, except I won't be doing much actual running with it.
