The equipment packs seem like a wonderful add-on, especially when I have two or three characters that are for farming and are still used on occasion to actually play the game (such as my raptor farming ele or my 55ss necro).
It can be annoying to have an entire set of armor sitting in my last bag with all the books that can't be put in a simple book bag

Now seeing as they vary in sizes there may be those that carry a simple main/off hand item set (such as a rack for your backpack with staves and swords or something like that) Whereas others may be big enough for a wardrobe of armors and an armory of weapons (vamp, zealous, poisonous, fiery, icy, etc.)
I'm thinking that these packs may only hold customized items.
Though I'm hoping that they can carry any weapon or armor. This way it can serve the bonus purpose of holding all those useless weapons that drop so I can use it like an added bag.
