The 2Go bottle features a vacuum valve for vacuum-sealing smoothies and beverages with the Bosch VitaMaxx vacuum mixer. Vacuum-sealed drinks last at least twice as long in the refrigerator compared to those without vacuum sealing. The 0.5-liter bottle fits in car and bicycle cup holders. It is made from durable, shatterproof, and BPA-free Tritan and is easy to clean in the dishwasher.
