The Yeti Rambler Mug is a versatile and practical choice for camping and on-the-go adventures. Its double-walled, vacuum-insulated design keeps your hot or cold beverages at the perfect temperature while protecting your hands. The large opening cools drinks faster but is easily covered with the included MagSlider™ lid. Plus, it's dishwasher safe for convenience. Please note, the magnetized lid is not leak-proof.
