Swim-Proof
Fitbit Flex 2 is the first swim-proof device from Fitbit, meaning it is water resistant to 100 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.

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.

Materials
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.

Environmental Requirements
Operating temperature: -10° to 45° C
Maximum operating altitude: 9,144 m

Syncing & Notifications
Using Bluetooth LE wireless technology, Fitbit Flex 2 sends smartphone notifications and syncs automatically to computers and 200+ mobile devices. Smartphone notifications may require Android 5.0+.

Syncing range: Up to 6.1 m
Syncing requires Bluetooth LE and Internet connection. Windows 10 computers that do not have Bluetooth LE will need a wireless sync dongle in order to sync.

Syncs with Mac OS X 10.6 and up, iPhone 4S and later, iPad 3 gen. and later, Android 4.3 and later, and Windows 10 devices.
