It's the first and only soft and very light coded transmitter. The Polar WearLinktm combines superior Polar technology with a new fabric design. The electrodes that pick up the heart's signals are engineered right into the fabric strap. The result is a superior fit for any individual body shape, providing revolutionary comfort and full freedom of movement. The Polar coded technology ensures that the user picks up only their heart signal, and not the signal of another heart rate monitor nearby. Wit
