Go big or go home... or go anywhere, because this is a tumbler that's made to actually fit in a cup holder. Imagine that. Stainless steel. 20 ounce capacity. No-sweat exterior and double wall, vacuum insulation to keep hot and cold drinks at optimal temperatures. The included all-new shaded splash-proof lid lets you know exactly how much drink you have and the flip-top closure resists spills and is straw friendly.
