Swim-Proof
Fitbit Flex 2 is the first swim-proof device from Fitbit, meaning it is water resistant to 50 meters. 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 Flex 2 in a hot tub or sauna. See www.fitbit.com/productcarefor more details.
Care
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.

The Fitbit Flex 2 wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. Flex 2 also has a surgical-grade stainless steel clasp.
