Last night I took a long hard look at my first ul pack, a gregory advent pro, and decided, I was going to cut it up :-). I never use it, it was 2lbs 10oz in size large, so I cut off basicaly everything except the side pockets, now the weight is 2lbs.
sadly, I will still never use it and now cant sell it. oh well, mabey for an expedition snow shoeing trip in the future I will need the volume? but for even a week, I dont need more than 2200cu in.
any way, it is a good front loader for a lightweight backpacker, but 1000 cu in too large for me. :-)
