The Tennis Performance Bra, which is part of the Women's Adidas by Stella McCartney collection, is both boob and health supportive. It is a hi-tech piece of sports gear that monitors the wearer's heart rate and calories burnt while on the court. It is equipped with a built-in miCoach heart sensor.
When synced with the Adidas miCoach app, the Tennis Performance Bra data can be used to track people's progress. It is made out of CLIMALITE fabric that draws sweat away from the wearer's skin and has a mesh insert in the front that targets airflow.
The Tennis Performance Bra joins a roster of equally helpful sports gear, which have all been designed to better optimize a person's workouts and athletic activities.
