Clean, thoughtful design equals versatility and performance. This is the concept that drove the development of Klean Kanteen's new TKPro. This 100 percent plastic-free thermal Kanteen utilizes an innovative 360-degree pour-through design to make transferring beverages, steaming or iced, into the integrated double-wall cup seamless every time. The TKPro is equally at home on a committed backcountry ski tour as it is pulling commute duty through the densest of urban landscapes. Representing the forefront of thermal performance at 38 hours hot and 100 hours iced, the TKPro is an elegant, hardwearing beverage transport solution. All while keeping plastic 100 percent out of the equation.
