Key Benefits
Created with inspiration from Olympic champion Jakob Ingebrigtsen's approach to training, this special edition COROS Heart Rate Monitor delivers accurate optical heart rate tracking, lasting comfort, and dependable multi-device connectivity.
Worn on the arm instead of the chest, it offers a more comfortable fit while delivering precise heart rate data through its latest multi-channel optical sensor.
It connects to up to three Bluetooth devices at once, making it easy to track workouts across multiple platforms. Wear detection allows automatic pairing, so it is ready to go as soon as you start moving. With up to 38 hours of active use or 80 days on standby, it supports consistent training without frequent charging.
The adjustable band ensures a secure fit, while the removable sensor makes cleaning quick and easy. Designed for everyday training, it keeps performance tracking simple and reliable.
Arm Size
Standard: 18-32 cm / 7.09-12.6 inches
Large: 24-43 cm / 9.4-16.9 inches
It's an extra thing to wear when running but is giving much more consistent data on my HR and is more comfortable for me than a chest strap. Syncs easily each time after the initial set-up and battery life is strong enough for multiple long runs.
