The 710 ml hydration bottle is equipped with a battery-powered app-enabled smart lid with a sensor tube that works in conjunction with the Thermos Smart Lid app and detects how much water is consumed throughout the day. The lightweight bottle, made with BPA-free Tritan copolyester, fits comfortably in the hand. The lid features an open drinking spout for high water flow, an integrated flip up carrying loop and a locking mechanism to keep the lid secure during transportation.
