Your character has a backpack in which up to nine items at a time can be stored. Also, there are six different body parts which can be protected by armour: head, neck, torso, shield arm, fingers and legs. In the lower right corner, you can see the contents of your backpack respectively the armour you are wearing. By selecting the actions "Armour" or "Backpack" either in the menu or by selecting the corresponding hotkey, you can switch between your backpack and your armour window.
