Every cloak has a contingent cause, a formal cause, a material cause, and a final cause.
The final cause of this cloak was that my first cloak doesn't travel well. I can't allow it to be folded or even creased, in case the electroluminescent ribbon is damaged. Carrying around a five-foot garment bag sucks. And if I tried to take it on an airplane, well, that would be nonstop fun. Since I live in North Carolina now, and have to fly to reach civilization, this is a real issue.
