Water Resistance
Water-resistant to 50 metres. After swimming or getting the band wet, we recommend drying 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 Fitbit Charge 4 in a hot tub or sauna.

Care
Give your wrist a rest by taking the band off every now and then. If the band gets wet or you sweat in it, remove and completely dry the band before putting it back on.

Materials
This tracker includes a plastic resin case and the band includes a stainless steel buckle. The classic band is made of a flexible, durable material similar to that used in many sports watches. The woven band is made from a comfortable polyester.
