Polar H1 Heart Rate Sensor Size M-XXL
Comfort is the key when training. Thatï¿¢ï¾€ï¾™s why Polar created the slim H1 heart rate sensor. It not only measures your heart rate but also seamlessly adapts to your body shape, so you can forget you are wearing it and focus on your exercise. Itï¿¢ï¾€ï¾™s even easier to put on than a pair of trainers! Soft textile material has a cloth-like feel to ensure comfort. Features an improved user-replaceable battery mechanism. The Polar H1 heart rate sensor features a 5kHz coded transmission that is compatible with most Polar products and Polar GymLink equipped exercise machines.
