The Travel Thermos was designed for people who lead conscious and flexible lifestyles —for those who appreciate the subtle flavors of single origin coffee and tea, or like to drink mineral water at the temperature that is just right for your body. The vacuum insulated tumbler has great heat and cold retention, and maintains the aroma and flavor of drinks for a long time. The cap feels smooth on the mouth as there are no screws, and is structurally designed to stop ice cubes and hot drinks from coming out vigorously so you can drink comfortably until the very last sip.
