Fitbit Blaze is sweat, rain and splash proof, but is not swim proof. We recommend taking it off before showering, as it's best for your skin if the band stays dry and clean.
If Fitbit Blaze 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.
The classic Fitbit Blaze wristband is made of a flexible, durable elastomer material similar to that used in many sports watches, and includes a surgical-grade stainless steel buckle and frame.
