Stanley 30 oz The Black Chroma Quencher H2.0 FlowState™ Tumbler. A band of iridescent shimmer defines the new Black Chroma Collection. The sleek prism effect makes each piece unique and adds a hint of sparkle next to the powdercoat matte finish. Featuring a glimmer that catches the eye, hydrate with Black Chroma. This Quencher H2.0 is generously sized (but not oversized) with an easy-carry, comfort-grip handle and a narrow base that will fit most cup holders. Long day of meetings? Rowing class? Trip out of town? Stanley's durable 30 oz tumbler, made with recycled stainless steel, is up to the hydration challenge. The double-wall vacuum insulation will keep your water cold for 9 hours and iced for 40 hours. And to cap things off, there’s an advanced FlowState™ lid that features a rotating cover with three positions: a straw opening designed to resist splashes with a seal that holds the reusable straw in place, a drink opening, and a full-cover top.
