Last year, Ralph Lauren introduced its wearable tech at the U.S. Open by outfitting the ball boys in nylon shirts that tracked their biometrics. Through silver fibers woven into the smart shirt it recorded their heart rate, steps, calories burned, breathing and stress levels and displayed the info via an app on an iPhone or computer screen. 

Now the fitted black T-shirt and PoloTech adaptive workout app will be available to purchase along with the rest of the Polo Sport collection. The new app uses the users information to draw from 10,000 combinations to produce custom video workouts.  

The PoloTech shirt will be released at the Ralph Lauren webstore and select retailers on August 27.
