Replacement bands for Fitbit trackers and smartwatches. Fitbit bands are not interchangeable across the whole range — each family uses its own connector, so a Charge band will not fit a Versa and a Versa band will not fit an Inspire. Match the band to your exact model, and pick Small or Large (or an adjustable style) to suit your wrist.Most Fitbit bands swap in seconds: press the small release latch on the back, slide the band out, then click the new one in. For model-by-model picks and compatibility, see our guide to the best Fitbit bands, or the best Fitbit Air replacement bands if you have the newer Fitbit Air.
