Product Description
ULTIMATE COMFORT AND PERFECT FIT. The ECG accurate, digitally coded Heart Rate transmitter with its completely textile composition ensures that it feels comfortable and fits perfectly. Using silver nylon yarns give the textile chest belt odor-free and antibacterial properties, even during the sweatiest of training sessions. Practical: the water-resistant COMFORTEX can easily be hand or machine-washed (104° F). It is compatible with all ONYX heart rate watches and the battery can be changed by hand in no time at all.
