The device envelops the wearer in a cloud of fog, simultaneously obscuring his or her identity and creating a temporary tranquil space.Everyone, at some point, has wanted to disappear for a while. With Cloud Cloak, you finally can—at the push of a button and in style. If nothing else, it seems like a great way to make a memorable entrance (or exit!).[via FashioningTech]
