How do I wear my Polar Loop?
Applies to: Polar Loop
Polar Loop comes with the Small-Medium size wristband pre-attached. If you want to change the size or switch to an accessory band, see How do I change the wristband of my Polar Loop for instructions.
Position the device correctly
Make sure the setting on which hand you wear the device is correct in the Flow app's device settings.
Wear the Polar device on top of your wrist, at least a finger’s width up from the wrist bone.
Make sure the oval mark on the frame is facing the thumb side of your wrist:

Secure the fit
- Adjust the wristband for a snug but comfortable fit and secure with the fasteners. The optical heart rate sensor on the back must stay in constant contact with your skin.
- You can check the fit by gently pushing the band upward from both sides. If the sensor lifts or you see the LED light shining, tighten the band slightly.
Keep it clean
The device is fully water-resistant, and the wristband is washable. You can safely clean both with a mild soap and water solution and rinse them under running water.
- You should regularly wash the device, the wristband and the skin on your arm – especially after you’ve been sweating.
- Use a mild soap and water solution and running water. Do not clean with alcohol, disinfectant or any other chemicals.

Every once in a while it’s a good idea to let your wrist have a breather, especially if you have sensitive skin. Loosen the wristband, for example, when your activity is low, to avoid skin irritation. You can also change the place of the device on your wrist a bit. From time to time, you should remove the Polar device completely from your wrist.
Success! ##
