A Japanese company, Haruyama Trading Co., has developed a suit that it claims protects the wearer from the deadly H1N1 strain of influenza.
The company has produced 50,000 of the suits and will start selling them on Thursday, according to a company spokesman.
The suit is coated with the chemical titanium dioxide, which reacts to light to break down and kill the virus when it comes into contact with it, according to Junko Hirohata. The chemical is a common ingredient in toothpaste and cosmetics.
The suit - which is indistinguishable from any other worn by Japan's legion of "salarymen" - comes in four colours and styles, which are medium grey, charcoal, navy and a grey pinstripe. It will go on sale for about £365.
