The one I have doesn't have a big pack on it, just a few pockets. The reason I don't like it is b/c I It's hard to deal with when I've got a stand on my back, back packs, bows, etc.

I think the ones that have the big backpack attached would be nice in some instances, but I like to take my backpack with me on other outings, such as scouting, etc, and I wouldn't want to take a quiver with me. I just want an arrow tube that will fit in my backpack and I can throw my pack around and not worry about arrows, etc.
