STANLEY Quencher H2.0 FlowState Tumbler | 40oz | Black

The original. The icon. The one that started a global hydration revolution — now in its most versatile colorway. The STANLEY Quencher H2.0 FlowState Tumbler in 40oz Black is the definitive everyday tumbler: bold enough to make a statement, versatile enough to go everywhere.

Constructed from recycled 18/8 stainless steel with double-wall vacuum insulation, the 40oz Quencher keeps cold drinks icy for up to 9 hours, iced drinks cold for up to 2 days, and hot drinks warm for up to 7 hours. The FlowState three-position lid offers a straw opening for sipping on the go, a drink-through opening for faster flow, and a full-close seal for leak resistance in your bag. The comfort grip handle makes carrying effortless, and the tapered base fits most standard car cupholders. The matte black finish is scratch-resistant and timeless — it looks just as good on day 500 as it did on day one. Dishwasher safe.
