Comfort is key when training. That’s why Polar created the Polar WearLink®+ 31 coded transmitter belt. 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 transmitter consists of an electrode strap and a connector, and with its new side-clip mechanism, it’s just as quick to put on as it is to take off.  

• Soft textile material feels like clothing on the skin
