STANLEY Quencher H2.0 Flow State Tumbler 40 oz Seafoam — double-wall insulated, rotating FlowState lid

The STANLEY Quencher H2.0 Flow State 40 oz Seafoam tumbler is a large, double-wall insulated travel cup with a rotating FlowState™ lid that offers straw, sip, and sealed positions for versatile, leak-resistant drinking.

This 40-ounce Quencher blends durable stainless-steel construction with an ergonomic handle and a multi-position lid engineered to adapt to how you drink. Built from recycled BPA-free stainless steel and finished in a soft seafoam color, it keeps beverages at their intended temperature for hours while resisting stains and odors. The narrow base fits most cup holders, and dishwasher-safe parts make cleanup quick for everyday life.

How does the FlowState™ lid make drinking easier during a busy day?

The rotating FlowState lid puts three distinct openings within reach: a straw-friendly seal, a direct drink spout, and a full cover for extra protection. Switching between positions is simple and secure, helping prevent splashes and reducing leaks when you’re on the move. The design keeps a reusable straw in place and minimizes spills when carrying between activities.

• Three-angle rotating cover: straw opening, drink spout, full-cover seal
• Straw seal resists splashing and secures the straw
• Full-cover position improves leak resistance for transport
• Comfort-grip handle for one-handed carrying

How long will cold or hot drinks stay at the right temperature?

Thanks to double-wall vacuum insulation, the Quencher preserves temperatures significantly longer than single-wall cups. Cold drinks stay chilled and iced for many hours; hot beverages stay warmer than in standard bottles. The stainless-steel body also prevents lingering tastes or stains, so flavors stay true over repeated use.

• Double-wall vacuum insulation reduces heat transfer
• Stainless-steel interior resists stains and odors
• Suitable for iced, cold, or warm beverages
• Narrow base fits most cup holders except the 64oz model

Is this tumbler easy to clean and sustainably built?

The tumbler and its lid are dishwasher safe, simplifying rinse-and-go maintenance after long days. It’s made from recycled BPA-free stainless steel for a smaller environmental footprint and long-lasting durability, intended to replace disposable bottles and single-use straws. The rugged construction supports daily wear without compromising performance.

• Dishwasher-safe lid and cup for effortless cleaning
• 90% recycled BPA-free stainless steel body
• Durable finish resists staining and retains freshness
