Wear & Care
Our products are meant to be worn all day and night*, so its important to follow a few simple guidelines as you wear and care for your device.
To keep your band clean and your skin happy, our board of certified dermatologists have outlined the following tips
FOR FITBIT FLEX 2 PENDANT ACCESSORY
Certain features like Auto Sleep Tracking and SmartTrack may be disabled when using this accessory. Classic accessory bands are the recommended accessory for high intensity workouts and sleep tracking.
Do not wear the Flex 2 Pendant accessory while sleeping or during high intensity activity, as doing so could create a choking hazard.
Flex 2 Pendant accessories contain magnets. Magnets may interfere with pacemakers, defibrillators, or other medical devices. Consult your physician and the manufacturer of your medical device before using to determine if these accessories are safe for you. If the accessories may be interfering with your pacemaker, defibrillator, or other medical device, do not wear the accessories.
Keep it Dry
While Fitbit devices are water resistant*, its not good for your skin to wear a wet band for long periods of time.
If your elastomer band gets wetlike after sweating or showeringrinse and dry it thoroughly before putting it back on your wrist.
Be sure your skin is dry before you put your band back on.
Even though Fitbit Flex 2 is swim-proof, its important to thoroughly dry your classic elastomer band and tracker, and remove any debris from your device after wear in the water, to avoid skin irritation. Please note that non-elastomer accessories should not be worn in water.
Dont Wear It Too Tight
Make sure your band isnt too tight. Wear the band loosely enough that it can move back and forth on your wrist.
If you use Fitbit Charge HR, Fitbit Blaze or Fitbit Surge, for better heart rate readings during exercise, we suggest wearing the band so its secure, but not too tight, and wearing the band higher on your wrist (about 2-3 finger widths above your wrist bone). Lower the band on your wrist and loosen it after exercise. Learn more.
Give Your Wrist a Rest
Prolonged rubbing and pressure may irritate the skin, so give your wrist a break by removing the band for an hour after extended wear.
If you have eczema, allergies or asthma you may be more likely to experience a skin irritation or allergy from a wearable device.
Whether you have the conditions above or not, if you start to experience redness or skin irritation on your wrist, remove your device. If symptoms persist longer than 2-3 days of not using your device, contact a dermatologist.
If you sweat for more than two hours while wearing your Fitbit band, be sure to wash your band and your wrist using the directions above to avoid skin irritation.
