If the band gets wet or if you sweat in it, remove and completely dry the band before putting it back on. Clean the band with a mild soap-free cleanser like Cetaphil
or Aquanil. Give your wrist a rest by taking the band off every now and then
Charge HR is sweat, rain and splash proof. However, the device is not swim proof or showerproof. With any wearable device, it's best for your skin if the band stays
