Chest strap without heart rate sensor!
With the Polar Pro Strap, thanks to the extra electrode, heart rate measurement is even more accurate, and the silicone points and the reinforced buckle allow comfortable and stable wearing.
The POLAR soft chest strap is the most comfortable heart rate monitor. The smart fusion soft tissues and adaptive electrodes make the heart signals extremely sensitive, so the heart rate sensor can track the speed and accuracy of the heart rate. Your training is compatible with the heart rate sensor, taking advantage of the same moments.
