The world’s smartest water bottle! Made from vacuum insulated stainless steel material, keeping drinks cold for up to 24 hours. The leak-proof straw lid has a protective cover to keep it clean. After setting the hydration goals, the LED smart sensor “puck” glows to remind you when it’s time to drink. Sync the bottle via Bluetooth® to the HidrateSpark® app in order to track the water intake and hydration level, or even to use the "Find your bottle" feature! BPA free.
