STANLEY Quencher H2.0 Flow State Tumbler — 40 oz Pomelo, 90% Recycled Stainless Steel & Vacuum Insulated

STANLEY’s Quencher H2.0 Flow State Tumbler (40 oz, Pomelo) is a large, recycled stainless-steel travel tumbler with vacuum insulation and a three-position FlowState™ lid designed for versatile, long-lasting hydration.

Built from 90% recycled stainless steel and engineered to cut down on refills, this 40 oz Quencher balances high capacity with practical everyday features: vacuum insulation to keep drinks cold (or hot) for hours, a narrow base that fits most cup holders, and an ergonomic handle with comfort-grip inserts for easy transport. The rotating FlowState lid lets you switch between a straw opening, a pour/drink opening, and a full-cover top for added leak resistance, making it flexible for commuting, workouts, or extended outings.

How does the FlowState lid make drinking easier throughout the day?

The FlowState lid gives three user-friendly positions so you can sip, pour, or fully close the tumbler without swapping parts. Its design secures the reusable straw and reduces splash while still allowing wide-open access when you want faster pours or big gulps.

• Rotating cover with straw opening that locks the straw in place for spill resistance
• Drink/pour position for larger sips and easier refills
• Full-cover top for extra leak resistance during transport

Will the 40 oz Quencher keep beverages cold for long trips?

Yes—Stanley’s double-wall vacuum insulation preserves temperature performance for extended periods, so iced drinks stay chilled and hot beverages retain warmth. The recycled stainless-steel construction also resists staining and odor retention that can occur with plastics.

• Double-wall vacuum insulation minimizes heat transfer for hours
• Metal interior prevents lingering smells and stains
• Durable recycled stainless steel withstands everyday wear

How portable and durable is the 40 oz size for daily use?

The 40 oz Quencher is designed to be large yet manageable: a tapered base fits most car cup holders and the comfort-grip handle makes it easy to carry. Constructed for long life, it replaces single-use bottles and holds up to active routines without dents or fading.

• Narrow base fits nearly all standard vehicle cup holders (except some 64 oz models)
• Ergonomic handle with comfort inserts for secure carrying
• 90% recycled stainless steel for sustainable, long-lasting use

How do I clean and maintain this tumbler for best performance?

The Quencher and its FlowState lid are dishwasher safe, making cleanup quick and hygienic. For occasional deep clean, remove the straw and rotate the lid to access seals; regular washing keeps the insulation performing and prevents residue buildup.

• Dishwasher safe components for simple cleaning
• Removable straw and lid parts for targeted rinsing or soak
• Stainless interior resists stains and odor retention over time

Who this is for: The 40 oz STANLEY Quencher H2.0 Flow State Tumbler suits people who want high-capacity hydration without sacrificing portability—commuters, fitness enthusiasts, travelers, and anyone replacing disposable bottles. It’s ideal if you need a rugged, eco-conscious bottle that holds long-lasting temperatures, fits a car cup holder, and offers flexible drinking options via the FlowState lid.
