A zero-g backpack uses anti-grav technology to enable the wearer to carry heavy items; items within the backpack effectively weigh nothing and do not add to the wearer’s carrying limits. The backpack can hold up to 100 lb of items. The backpack itself has a weight of 5 lb, however, and a zero-g backpack does not operate within another zero-g backpack – in fact, placing one inside the other destroys both items permanently, depositing their contents on the ground.
