Save some space by transforming your Rambler Bottles with the heat-locking, two-in-one companion - the Cup Cap. Not only is it compatible with every Rambler Bottle, but it also offers twice the functionality. As an insulated cap, it helps keep your coffee, tea, or even whiskey at the perfect temperature. And when you twist it off, you've got a double-wall vacuum insulated cup.
Our complete line of innovative bottle caps is compatible with all Rambler® bottles
Note! The Rambler Bottel (last picture) is not included.
