Three bags, feeding two
2004 said
Your quiver takes a bag slot and your pet eats more than you do, so you have three bags for everything else.
Forever says
Blizzard hasn't said whether quivers and ammunition return.
The guide is honest about the hunter's packing problem. One of your bag slots goes to the quiver or ammo pouch. A good share of what's left goes to pet food, because "you're feeding two after all."
It then recommends skinning as a profession, which fills the remaining space with leather. Nobody has ever felt so seen by a book.
Blizzard's posts about Forever don't say whether quivers and ammunition are back, so we make no claim either way.
Bags are how much you can carry. You start with one and collect up to four more, and you will always want a fifth.
