STANLEY Quencher ProTour Flipstraw Tumbler 20 oz — Black Fade, double-wall vacuum insulated & leak-resistant

The STANLEY Quencher ProTour Flipstraw Tumbler (20 oz) is a durable, leak-resistant cold-only cup that keeps drinks icy for hours with a built-in flip straw and comfortable carry handle.

Designed for daily hydration on the go, this 20-ounce Quencher blends Stanley’s rugged 18/8 stainless-steel construction with a flip-up straw lid and vacuum insulation to preserve chill. It’s finished in a black fade colorway and sized to fit most car cup holders while offering a textured comfort-grip handle. The tumbler is intended strictly for cold beverages and comes with clear cleaning and use guidelines to keep performance and safety intact.

How does the flip straw lid prevent spills and make sipping easier?

The ProTour flip straw lid snaps shut when not in use, creating a secure seal to reduce accidental spills. The straw flips up quickly for one-handed drinking, and the lid components assemble to form a leak-resistant system when closed correctly.

• Flip-up straw for fast, convenient sipping.
• Snap-shut lid that helps minimize leaks when closed.
• Designed to be fully leak-proof only when lid, spout, and straw are properly assembled.

How long will drinks stay cold in this 20 oz Stanley tumbler?

Double-wall vacuum insulation keeps cold drinks chilled for extended periods during everyday use. The stainless-steel body and vacuum barrier slow heat transfer so ice and cold beverages maintain temperature longer than single-wall cups.

• Double-wall vacuum insulation for prolonged cold retention.
• 18/8 stainless steel construction that supports temperature control.
• Works best with non-carbonated, cold beverages to maintain performance.

What care and cleaning should I follow to protect the finish and performance?

This tumbler is dishwasher-safe but avoid commercial-strength or high-heat dishwashers to preserve the finish and vacuum seal. For longer-lasting color and artwork, hand washing with mild detergent is recommended; soak with warm water and baking soda to lift stubborn stains.

• Dishwasher safe on normal household settings—avoid high heat and commercial machines.
• Hand wash with mild detergent to preserve painted finishes.
• Soak with warm water and baking soda for tough stains; remove lid while soaking.

Are there any liquids I should not use with this tumbler?

Yes. The Quencher ProTour is intended for cold beverages only. Avoid hot drinks, carbonated or fermenting liquids, citrus mixes, milk products, and baby food to prevent pressure build-up or lid failure.

• Do not use hot liquids—risk of pressure and lid ejection.
• Avoid carbonated and fermenting beverages that can build internal pressure.
• No freezing, no microwave or oven use to preserve material and function.
