Flex is the Fitbit for fashionistas! Style your Flex tracker the way you want, with bright accessory bands, or turn it into a fashion piece with the exclusive collection from Tory Burch. To change bands, simply pop the tracker out of the wristband and slip it into the accessory that best fits your personality. Flex is also the perfect tracker if you need a little motivation, as it lets you see how your day is stacking up, with LEDs that light up like a scoreboard as you get closer to completing your step, calorie or distance goal.
