As an individual with the good fortune of being born and raised in the United States of America, I can't say that I've ever witnessed a bombing or any other kind of terror-related attack, much less lived with the potential threat of such as a facet of day-to-day existence. Politics aside, many major conurbations in Israel are hotbeds of guerilla activity, and civilians are trained to heed air raid sirens with Pavlovian efficacy. Yet simply taking cover doesn't guarantee one's safety, an issue that designer Hila Raam tackled with her recent graduation project, the Rhinoskin.
Raam won the Best Final Project award for the backpack, which incorporates kevlar panels—discreetly integrated into an otherwise unassuming bag design—to protect one's head and torso in dangerous situations. Thus, it is an unobtrusive solution for residents of "countries or areas that are under daily attacks, protecting against debris and impact created from missile and rocket attacks."
Seeing as the detachable vest portion can be used as a standalone safety garment—the backpack can be used on its own as well—I imagine it could be adapted for additional applications in emergency response or other tactical situations as well. Of course, kevlar body armor is easy enough to find on the Internet—a quick search suggests that pricing starts around $200—so the question is whether there are other scenarios in which there is an advantage to an easily-deployed partial covering, i.e. for lying prone; I can only assume that the hood offsets any cost savings from the lack of a chest panel. It's certainly an interesting concept, but I'd be curious as to whether it would need further refinement or tweaking to bring it to market.
