We’ve brought you other crime-prevention apparel and gadgets in the past, such as the No-Contact Jacket and the Cell Phone Stun Gun. Joining the ranks is the meshy Knife-Proof T-Shirt. It’s made of “ultrahigh molecular weight polyethylene fiber”—akin to the “aramid fiber” used to create body armor. With that caliber of fabric, we’re pleasantly surprised to learn the tee is also machine washable. The potentially life-saving tee will be available in Japan during June in both a short-sleeve ($190-$522 USD) and long-sleeve ($220-$590 USD) versions. However, the manufacturer, Nihon Uni, does not seem to have a website to order from.
