Fitbit Charge 2 is sweat, rain and splash proof. However, the device is not swim proof or shower proof. With any wearable device, it’s best for your skin if the band stays dry and clean.
If the 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.
Fitbit Charge 2's wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. Fitbit Charge 2 also has a surgical-grade stainless steel buckle.
