Water Resistance

Fitbit Flex is sweat, rain and splash proof. However, the device is not swim proof. We also recommend taking Fitbit Flex off before showering because, as with any wearable device, it’s best for your skin if the band stays dry and clean.

If Fitbit Flex gets wet or if you sweat in it, remove and completely dry the band before putting it back on. Give your wrist a rest by taking the band off every now and then, and regularly clean your band and wrist. Learn more.
