Fashion brand Ralph Lauren has launched a smart polo shirt, in partnership with Canadian wearable firm OMSignal.

First seen at the US Open last August, the PoloTech shirt will go on sale at Ralph Laurens site and flagship store in New York from 27 August, as part of an athletic-focused Polo Sport range.

The shirt uses silver fiber sensors to collect biometric data including heart rate, energy ouput and stress levels. These can be viewed through a paired iOS app – also available for the Apple Watch – which can be used to create customised work-outs.

“The Ralph Lauren PoloTech shirt will change the way you look at fashion and apparel. It will give you knowledge you can use to lead a better life,” said David Lauren, Executive Vice President of Global Advertising, Marketing and Corporate Communications. “This is a bridge between technology, fitness and style that approaches wellness and well-being in comprehensive and complementary ways. It will touch many parts of your life.”

Ralph Lauren isnt the first clothing brand to launch a piece of wearable technology this week – we reported on Speedos partnership with Misfit on Tuesday.
