Ralph Lauren has perfected the polo shirt, denim, handbags, heck, even the Reuben sandwich. He’s now taking on your workout. The PoloTech Shirt is billed as the first luxury smart shirt—a Fitbit with sleeves, really. The $295 snug black tee (only for men now) contains chest sensors and an accelerometer and gyroscope that capture real-time movement and vitals. Naturally, it’s all streamed directly to your iPhone or Apple Watch and the PoloTech app, which also offers personalized video training sessions. What comes after the gym? Air-dry the shirt—and check the app for feedback.
