It looks like a large bottle cage. But it has a strap. So you can put a small bag or whatever on there and add some easily removable storage.
Are you talking about the
Topeak Modula XL? I have one of those, and it's great for 1.5L plastic bottles, but the strap is designed to barely fit around a bottle-cap, it would take some cleverness to adapt that to like a bundle or something.
