Adjustable elastic strap with soft fabric and adaptable electrodes that detect your heart’s electrical signals and pair with a wide range of heart rate sensors (ANT+, Bluetooth 4.0, 5.3K). Key benefits Comfortable, secure fit: The elastic, adjustable strap conforms to your body so the sensors stay in place during movement without excessive pressure. Sensitive signal capture: Soft fabrics and adaptable electrodes provide close, stable contact with the skin to pick up your heart’s electrical signals reliably. Broad compatibility: Works with many heart rate sensors and devices using ANT+, Bluetooth 4.0, and 5.3K, making it easy to connect to watches, bike head units, phone apps, and trainers. Reduced irritation: Soft, flexible materials minimize chafing and discomfort for longer wear. Simple pairing and use: Designed to deliver clear electrical signals to compatible heart rate monitors for accurate readings. How it solves common problems Eliminates signal dropouts: Stable electrode contact reduces interruptions that can occur with loose or stiff straps. Minimizes discomfort during activity: Soft fabric and an adjustable elastic design prevent digging or rubbing that interrupts workouts. Avoids compatibility headaches: Supports ANT+, Bluetooth 4.0, and 5.3K so you can pair with most commercial heart rate devices without buying multiple accessories.
