Since 2010, Corkcicle have created innovative barware, then found their way into the hydration space, and today, continue to push the boundaries of keeping things cool in style. Their mission is still the same: elevate the moments that matter. Corkcicle canteens and tumblers use a first-of-its-kind, proprietary layer of insulation. In between two walls of stainless steel, there is a third layer that keeps drinks cold for up to 20 percent longer than other insulated bottles and cups.
