Yeti Rambler 20 oz. Tumbler
The Yeti Rambler 20 oz. Tumbler features double-wall vacuum insulation to keep your beverage hot or cold. Included is the MagSlider lid which adds an extra barrier to prevent heat and cold from escaping and to prevent the entry of debris and exit of splashes. The MagSlide lid is ideal for cleanliness, but is not completely leakproof, so the tumbler needs to be kept upright.
