The HighWave JOEmo XL Insulated Beverage Travel Tumbler has a patented technology that will keep your drink hot or cold for 6 hours. Named the Time Capsule, this 16 ounce stainless steel tumbler will put the temperature of your drink in a 'time capsule' state. The sleek stainless steel design is visibly attractive and fits comfortably into all drink holders. The on/off top push plate allows you to easily open and close your tumbler with one hand and the vacuum seal renders it spill-proof. Note: Highwave no longer includes a carrying case or tea basket with the JOEmo XL.
