The COROS Heart Rate Monitor Band is the official replacement and spare strap for the COROS Heart Rate Monitor, available in Grey, Lime, and Orange. If your existing band is worn, you want a spare for back-to-back training days, or you simply want a fresh colour, this is the direct replacement. It's compatible with the COROS Heart Rate Monitor only — not with heart rate monitors from other brands.
The band is made from a blend of polyester fibre, nylon, and spandex, combining breathability, stretch, and durability for comfortable extended wear during training. The snug, elastic fit keeps the heart rate monitor sensor in firm contact with the skin, which is important for optical heart rate accuracy — a loose or shifting band is one of the most common causes of inaccurate HRM readings. The band accommodates a wide range of arm sizes: the standard size fits 18–32cm and the large size fits 24–43cm arm circumference. Check your arm measurement before selecting a size. The band features the COROS "EXPLORE PERFECTION" branding.

Which size should I choose?
Measure the circumference of your upper arm where you wear the heart rate monitor. If your measurement is between 18–32cm, choose standard. If it's between 24–43cm, choose large. If you fall in the overlap (24–32cm), either size will fit — choose based on whether you prefer a snugger or more relaxed fit.
Is this compatible with all COROS watches and accessories?
No — this band is specifically for the COROS Heart Rate Monitor (the arm-worn optical HRM device). It is not a watch band and is not compatible with COROS watches such as the PACE Pro, PACE 3, or PACE 4. For watch bands, see the COROS PACE Pro Nylon Band.
How do I attach the heart rate monitor to the band?
The COROS Heart Rate Monitor clips into the band's sensor pocket. Ensure the sensor is seated firmly and the optical sensor window faces the skin. Position the band on your upper arm with the sensor on the inner (bicep) side for best contact and accuracy.
How do I wash the band?
Hand wash in cool water with mild soap and allow to air dry. Do not machine wash, tumble dry, or iron. Regular washing after sweaty sessions will extend the band's life and maintain hygiene.
