The YETI Rambler 20 oz Travel Mug Black (591 ml) is a "serious" travel mug: super solid stainless steel construction, the right size for a large coffee or tea, and a black finish that looks good everywhere (car, office, travel). The 591 ml capacity is perfect if you want to drink a lot without refilling every half hour, and the travel mug format is very convenient for cup holders and daily commutes. It's the classic mug you can abuse without a second thought and that always remains reliable. SKU: 70000002323
