I've only sparingly used a fanny pack alone not while also wearing a loaded backpack with a true hip belt w/ hip belt pockets for backpacking. On day hikes I often find a fanny pack alone acceptable as a minimalist. How does adding a fanny pack not get in the way when also wearing a pack as depicted? It also seems it would make it hot and sweaty and confining around the waist a situation some find prone to chafing around the waist wearing all this. If one's backpacking modus operandi are regular stops doesn't removing such a layered set up and then having to put it back on become onerous? Asking.
