Polar Loop Activity Tracker with H7 Heart Rate Sensor Bundle

Get 24/7 activity tracking—including heart rate data—with this Loop Activity Bundle from Polar. The Loop is a wrist-worn tracker that works with the Polar Flow iOS/Android app and Polar Flow web service to provide several useful features and feedback about your activity levels, including activity intensity, post-workout analysis, and more. Expanding upon that analysis, the H7 Heart Rate Sensor measures your heart rate data and wirelessly sends it to your Loop for an even more detailed report of your activity performance.
