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?
without a container even though this doesn't exceed my encumbrance limit?" or "Do the encumbrance rules require me to use containers once weight exceeds a certain point?"); providing more information than might be necessary can be helpful (i.e. what's your strength score and class level?); identify sections of the rules that you've looked at already and discuss how they relate to your question (i.e. encumbrance rules in the PHB don't seem to address containers).
