This hakpack adds a variety of clothing additions that help make adventurers look more like well... adventurers - amongst the add ons are belt and back fitted scabbards (Bioware seems to think you keep swords in your backpack without any kind of sheath), backpacks, satchels and bags of holding (Again Bioware models seem to keep all their belongings in their back pocket), overall it just makes your characters look more convincing.
