I had to carry a bear container last time I went out for the better part of a week. I know there is good reason for that, but my usual (REI Flash)50 liter pack wasn't big enough and the container didn't strap on or fit in it hardly at all. So I went back to my large (80 L or 5000 cu in?) Jan Sport pack that weighs more than 4 pounds. It worked very well, has lots of pockets and is very comfortable. However I could probably cut the weight of the pack in half except I'm seeing the price tag of ultralite pack between $200 and over $400. Is there, are there, ultralite packs in the 60-80 liter range that don't cost an arm and a leg? I'd like some suggestions if you have any.
