Fitbit watch strap loops

The Fitbit Charge 3 and Charge 4 are designed to be worn around the clock, and the loop that holds the strap end is often the first part to give way. Once it tears, the strap end sticks out, catches on sleeves and the tracker can come undone. These Fitbit compatible loops let you repair the strap rather than replace it.

They are compatible replacement parts, not official Fitbit accessories. Made from soft, sturdy silicone, they are unaffected by water and sweat, comfortable against the skin and easy to keep clean. Two models are covered:

• Fitbit Charge 3
• Fitbit Charge 4

It is always worth checking the exact model of your tracker in the Fitbit app or on the back of the device before choosing. If you are using 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.

No tools are required: unfasten the strap, slide the loop on and position it just after the buckle. Silicone stretches slightly as it goes on and then grips firmly. Rinse with water and a little mild soap and let it dry before wearing it again, including overnight for sleep tracking.
