At least you could save yourself from knife attack. You might be thinking what I am talking about? Let me tell you, in the world where people are short tempered, aggressive and didnât hesitate to even hit for simple cause, this shirt can save your life. Yes! Japanâs Nihon Uni, a uniform manufacturer company in Chuo Ward, Osaka has created a shirt that is three times stronger than usual cotton t-shirt. To provide more strength to the shirt, the ultrahigh molecular weight polyethylene fibers have been used to make it equal to the armid fibers that are used in body armor. This shirt doesnât expect extra care from you. You can wash it in Washing machine. You can buy a short-sleeved T-shirt for 19,000-52,000 yen ($190-522), and for a long-sleeved t-shirt, you have to shell out 22,000-59,000 yen ($220-590). This shirt will hit Japan Market in the month of June.
