This classic band is made of a flexible, durable elastomer material similar to that used in many sports watches and includes an aluminium buckle that matches either the band or tracker.
Fitbit Charge 4 & Charge 3 classic bands are water-resistant to 50 metres. After swimming or getting the band wet, we recommend drying off the band because, as with any wearable device, it's best for your skin if the band is clean and dry. We do not recommend wearing it in a hot tub or sauna. See www.fitbit.com/productcare for more details.
If this band 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. Learn more.
