The Lighter1 "Big Daddy" sold at REI weighs 2#13oz (total weight). My Bearikade weighs 1#14oz for a similar capacity. The Ursack weighs considerably less.

Balazacom- A BearValut may fit fine in a larger man's pack, but have your wife carry it in her pack, or a woman's small (my size) PLUS cook gear, at it IS a problem. The weight distribution is NOT as efficient as putting the food sack up against your back and then fill the remaining half of the pack with lighter clothing. If you use the rectangular packing cubes for food you can quite efficiently get that weight really close to your center of gravity. It does make a difference. It seems to be the assumption of pack manufacturers that a small woman always goes with a big guy who carries the bear can! Not True!!
