Vessel Coat Doubles as a Backpack, Triples As a Tent

It's a coat, backpack and tent all-in-one.
During warm weather, the coat can be folded and strapped around the wearer as a backpack for easy transport. When it's time to set up camp, the interior lining can be stretched out and pegged—creating a private, protective cocoon. Again, it's only a concept at this point—but I've watched enough Suvivorman and Man vs. Wild to know that something like this could be useful in the real world.
