Yeti Rambler Cup Cap

Convert your Rambler® Bottle into a fully insulated thermos.

Save space and add versatility with our heat-locking, two-in-one Cup Cap. Designed to fit every Rambler® Bottle, it provides dual functionality: use it as an insulated lid to preserve the temperature of coffee, tea, or whiskey, then twist it off to reveal a double-wall, vacuum-insulated cup for drinking on the go.

Do not use the Rambler® Bottle Cup Cap with carbonated beverages or to store food or perishables. For details on proper use and safety, please see our FAQ page.
