STANLEY Quencher ProTour Flipstraw Tumbler 40 oz Toast VRT — 18/8 Recycled Stainless, Double-Wall Insulated Cold-Only

The STANLEY Quencher ProTour Flipstraw Tumbler (40 oz, Toast VRT) is a leak-resistant, double-wall vacuum insulated cold-only tumbler built for long-lasting ice retention and comfortable everyday carrying.

Bring dependable chilled hydration to your day with a tumbler designed for active use and easy cleaning. This 40 oz Quencher pairs Stanley’s durable 18/8 recycled stainless steel construction with a flip-up straw lid and a textured comfort-grip handle so you can sip on the move. It’s intended for cold beverages only and offers dishwasher-safe convenience when you follow the care guidance—avoid high-heat commercial cycles and harsh chlorine detergents to preserve thermal performance and finish.

How does the ProTour Flipstraw keep drinks cold during long outings?

The tumbler uses double-wall vacuum insulation to slow heat transfer and retain ice for extended periods. That means your water, iced coffee, or sports drink stays noticeably colder than in single-wall bottles, especially during long commutes or outdoor activities.

• Double-wall vacuum insulation reduces heat exchange for hours of cold retention.
• 18/8 recycled stainless steel resists temperature changes and flavor transfer.
• Wide 40 oz capacity holds more fluid between refills, minimizing stops.

Is the flip straw lid really leakproof and simple to use?

The ProTour Flipstraw lid is engineered to snap closed and seal the drinking spout, helping prevent spills when properly assembled and tightened. Flip the built-in straw up to sip, then fold it down and click the lid shut for travel; correct assembly is essential to achieve full leak protection.

• Flip-up built-in straw for quick, one-handed sipping.
• Snap-to-close design secures the spout when not in use.
• Lid, spout, and straw must be fully tightened and assembled for leakproof performance.

What cleaning steps keep the tumbler performing and looking good?

The Quencher is dishwasher-safe under normal household settings, but hand washing preserves painted finishes longer. Avoid commercial-strength dishwashers and detergents with high chlorine or bleach levels, and remove the lid during any long soaks to prevent pressure buildup.

• Hand wash with mild detergent and warm water for best finish preservation.
• Dishwasher-safe on standard cycles; avoid high heat commercial machines.
• Soak stubborn stains overnight with warm water and baking soda; remove the lid while soaking.

What should I avoid putting in this tumbler?

This tumbler is intended strictly for cold use. Do not fill with hot liquids, carbonated, citrus, fermenting beverages, milk products, or baby food—these items can cause pressure buildup, lid failure, or other safety risks.

• No hot liquids—risk of pressure and lid ejection.
• Avoid carbonated and fermenting drinks to prevent pressure buildup.
• Do not freeze; freezing can alter vacuum performance and functionality.

Who is this for? The STANLEY Quencher ProTour Flipstraw Tumbler (40 oz, Toast VRT) fits people who move a lot—commuters, gym-goers, road-trippers, and outdoor enthusiasts who want a high-capacity cold tumbler that’s comfortable to carry and built to last. It’s also a solid choice if you prefer a straw-sipping experience and a design that balances rugged stainless steel durability with dishwasher convenience. If you need an insulated container suitable for hot beverages, or you regularly use carbonated or fermenting drinks, choose a different Stanley product designed for those purposes.
