Polar watch strap loops

The Polar A360 and A370 activity trackers are worn all day and through every workout, and the small loop holding the end of the strap eventually wears out. Once it splits, the strap end no longer lies flat and the tracker can come undone. These Polar compatible loops let you fix that yourself.

They are compatible replacement parts, not official Polar accessories. Made from soft, durable silicone, they can be fully immersed in water and stretch slightly without giving way, so they slide on easily and then hold the strap firmly. Two models are covered:

• Polar A360
• Polar A370

Check the exact model of your tracker in the companion app or on the back of the device before choosing, as strap shapes differ between Polar models. If you have switched to a third-party strap, measure its width in millimetres at the point where the loop sits and choose a loop with the same inner width from the widths section, where silicone loops come in many colours.

Fitting needs no tools or particular skills: unfasten the strap, slide the loop on and push it into position just after the buckle. Rinse with water and a little mild soap after training and let it dry. With a new loop in place, the strap end stays neatly tucked away during exercise and throughout the day.
