What to Compare Before Buying
- Sensor compatibility: This strap is meant for Polar H10, H9 and H7, plus several other named heart rate monitor products. Match the sensor model before ordering.
- Fit range: The stated wearable size is 29.5" to 43.3". Compare that range with the chest size you need to cover.
- Intended replacement use: This is a replacement strap, so confirm that you need the strap itself and not a full sensor kit.
- Color and material: The strap is black and made from silicone and fiber. Check whether that matches the version you want.
Before You Decide
Confirm the sensor model, the 29.5" to 43.3" fit range, and the MyZone exclusion before choosing an offer. If you need the complete heart rate monitor system, make sure the strap-only replacement matches what you already own.
