This great Stainless Cup Cap from Yeti will fit onto all Yeti Rambler water bottles turning them into thermos flasks.

But the genius doesn\’t end there. If you twist the cap off you are left with a twin walled vacuum, insulted cup. Perfect for that cup of coffee, or tea when you sit down for a well earned break.

The cap can be broken down into three parts which are all dishwasher safe for that thorough deep clean and like all Yeti Rambler parts and bottles, comes with a reassuring 5 year warranty.
