From your heart rate and breathing rate to your body temperature and body movement, the patented Prevayl Sensor tracks it all to help you make the smartest fitness decisions.

At 1,000 data points per second, the Sensor processes more data than any other wearable on the market and distills them to give you the most accurate insights into your fitness and performance.

It fits into each garment in our SmartWear® collection, allowing you to start building your own connected wardrobe.

Designed to disappear into the garment, this is the wearable that won’t weigh you down.
