Constructed of 90% recycled stainless steel for sustainable sipping, the Stanley Quencher H2.0​ Flowstate Tumbler 40OZ helps you reach your hydration goals with fewer refills. Working, workouts, road trips — you’ll want this Stanley tumbler always by your side. Thanks to Stanley’s vacuum insulation, your water will stay cold for 11 hours, 2 days when iced. The advanced FlowState™ lid features a rotating cover with three positions: a straw opening designed to resist splashes while holding the reusable straw in place, a drink opening, and a full-cover top. The ergonomic handle includes comfort-grip inserts for easy carrying, and the narrow base fits just about any car cup holder. Lastly, every piece of this stainless steel water bottle is dishwasher safe.
