The Nihon Uni company a uniform manufacturer in Chuo Ward, Osaka, has developed a T-shirt intended to supply protection against knives, following an increasing number of malicious crimes that have victimized children and late-night convenience store clerks. The company used a slightly thick fiber that is three times stronger as cotton for the T-shirt. The strength of the T-shirt made from ultrahigh molecular weight polyethylene fiber

is equal to that of aramid fiber used in body armor. The lightweight T-shirt is machine-washable and provides superior protection from slashing attacks. Be careful as the mesh fabric can be punctured by a sharp point.

The short-sleeved version of the T-shirt costs 19,000-52,000 yen($190-522), while the long-sleeved variety ranges from 22,000-59,000 yen ($220-590) and will be available in Japan from June.
