Comfort is the key when training. That’s why Polar created the slim H1 heart rate sensor. It not only measures your heart rate but also seamlessly adapts to your body shapes so you feel as if it’s not even there. The heart rate sensor consists of an electrode strap and a connector, and with its hook mechanism, it’s just as quick to put on as it is to take off.
