Easier to wear than a chest strap, our soft fabric strap lies flat around your arm and locks into place with its textured surface. Its slim design prevents snagging on clothing or gym equipment, so you'll almost forget you're wearing it.

Adjust the durable elastic band for perfect placement and tension by simply sliding the buckle until it feels comfortable. The secure hook-and-loop closure allows you to quickly remove the sensor for easy cleaning.

Our latest-generation multichannel optical sensor delivers high signal quality. Housed in a sturdy yet sleek housing and protected by a scratch-resistant cover, our advanced sensor will provide years of reliable and accurate heart rate data.

Optical heart rate sensors work best when held firmly against your skin. Our band is designed to rest the sensor snugly against your arm, preventing external light from entering and maintaining strong signal quality regardless of your activity.

With 38 hours of full power or 80 days of standby time on a single charge, the COROS Heart Rate Monitor is built to last. Check your battery level on your COROS watch or app, and use the magnetic cable for quick charging.

With built-in wear detection, the COROS Heart Rate Monitor automatically turns on and off based on when it's being worn. This allows you to automatically connect to your paired devices every time you start a workout.

Designed to work seamlessly with your favorite COROS watches and app, it can also be paired with up to three devices simultaneously, including non-COROS watches and other Bluetooth-compatible indoor trainers, bike computers, and more.

Optical heart rate sensors use light to measure blood flow in capillaries beneath the skin. The top of your wrist is a convenient location for a watch, but a challenging one for even the best sensors. Wearing it on your arm provides our optical sensor with optimal blood flow to collect heart rate data with the same accuracy as a traditional chest strap.
