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.
