Stanley The Quencher H2.O FlowState Tumbler Black

This Quencher H2.0 is generously sized with an easy-carry, comfort-grip handle. Long day of meetings? Rowing class? Trip out of town? This durable 64 oz tumbler, made with recycled stainless steel, is up to the hydration challenge. The double-wall vacuum insulation will keep your water cold for 15 hours and iced for 60 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.
