Made using oak wood and stainless steel, the Kole Thermal Flask reimagines what a flask should look like. With a unique bullet shape, the Kole Flask is perfect to slide into your backpack pocket for a daily commute, or your jacket pocket for a more formal affair. The top cap even doubles as a cup, useful for a quick nip of whiskey or a shot of espresso. Available in Oak, Walnut, or Mahogany.
