STANLEY Quencher ProTour Flipstraw Tumbler 40 oz — Dried Pine, Vacuum-Insulated, Leak-Resistant

The STANLEY Quencher ProTour Flipstraw Tumbler (40 oz, Dried Pine) is a leak-resistant, double-walled insulated cup designed to keep cold drinks chilled for hours while offering a comfortable grip and a flip-up straw for easy sipping.

This 40-ounce Quencher blends rugged construction with everyday convenience. Built from recycled 18/8 stainless steel and finished in a muted dried pine hue, it’s meant for cold beverages only and is optimized for long-lasting chill thanks to its vacuum insulation. The flip-straw lid snaps closed for secure transport, and the textured handle plus slim base make it effortless to carry and fit in most cup holders.

How does the flipstraw lid keep drinks from spilling?

The ProTour lid features a flip-up straw mechanism that seals when closed, reducing accidental leaks during movement. Proper assembly and ensuring the straw and lid are fully locked are important for maximum leak resistance.

• Flip-up straw for one-handed sipping and quick closure
• Seal design minimizes spills when lid is snapped shut
• Leakproof when lid, spout, and straw are correctly assembled

How long will cold beverages stay chilled?

Double-wall vacuum insulation is engineered to maintain low temperatures for extended periods, making cold water and iced drinks stay refreshing throughout the day. Avoid using hot liquids, carbonated, citrus, or fermenting beverages, which are outside the product’s intended use.

• Vacuum insulation preserves cold for hours
• 18/8 recycled stainless steel construction resists temperature transfer
• Keep to cold beverages for best thermal performance

What cleaning and care steps keep the tumbler performing well?

This tumbler is dishwasher-safe under normal household conditions, but hand washing will better preserve paint and finishes over time. Avoid commercial-strength dishwashers or high-heat cycles and never use bleach or chlorine-heavy detergents to protect the vacuum seal and appearance.

• Dishwasher safe on typical home settings; hand wash to preserve finish
• Use mild detergent and warm water for routine cleaning
• Soak stubborn stains overnight with warm water and baking soda; remove lid while soaking

Will the Quencher fit in my car cup holder and everyday routine?

The tapered base is designed to slide into most standard cup holders while the textured comfort-grip handle makes carrying comfortable whether you’re commuting or heading out on an adventure. Its 40-ounce capacity cuts down on refill frequency and suits long days on the go.

• Narrow base fits many vehicle cup holders
• Comfort-grip handle for easy transport
• Large 40 oz capacity reduces refills during activities
