Flex 2 Fitness Wristband: A slim, swim-proof fitness wristband that's ready to go wherever life takes you. The ultra-thin, removable tracker hides in bands, bangles and pendants, so you can wear it in a way that's all your own. Automatic all-day activity and sleep tracking show you how your entire day adds up, and SmartTrack~ automatic exercise recognition records your exercises for you. The discreet progress display uses color-coded LED lights to keep you connected to calls, texts and Reminders to Move. Plus you don't have to worry about getting it wet-whether you're swimming in the pool or running in the rain.
