How much gear can you hold with out a backpack or any container? If your a fighter and pick leather armor, longbow, twenty arrows, rapier, shield, two handaxe, and an explore's pack. wear the armor and the pack, hold the sword and shield, tuck the handaxes in your pants, loop the bow around your torso, stick eight arrows between your toes two up your nose and ten in your mouth. So you can hold all that sure but you can't do anything.
Do you even need containers?
