“It weighs less than 4.5 oz and is made from the same material as the rest of the company’s line of compression-based apparel.
Yet just below the sternum, the shirt also contains a removable sensor pack called a “bug” that holds a triaxial accelerometer, a processor and 2 gigabytes of storage. The information collected can be broadcast via Bluetooth to smartphones, iPads and laptops so that scouts and trainers can view the power and efficiency of each athlete’s movements. Heart-rate and breathing-rate monitors are placed on both sides of the sensor pack, helping to gather even more intel from the body’s core.”
