STANLEY Quencher ProTour Flipstraw Tumbler 1.18 L Coastal Teal — Leakproof, Double-Wall Insulated

The STANLEY Quencher ProTour Flipstraw Tumbler (40 oz) is a leakproof, double-wall vacuum insulated travel cup with an integrated flip straw and comfort handle for all-day cold drinks.

This 40-ounce Quencher from STANLEY updates the brand’s classic, oversized tumbler with the ProTour Flip Straw lid to make sipping faster and spills less likely. Built from 18/8 recycled stainless steel with double-wall vacuum insulation, it keeps beverages cold for hours while the narrow base fits most car cup holders. The textured comfort-grip handle and two-tone lid give it a comfortable, everyday feel—useful for commutes, workouts, road trips, or desk-side hydration.

How does the ProTour Flip Straw lid prevent spills and make sipping easier?

The ProTour Flip Straw lid features a built-in straw that flips up for drinking and snaps closed to reduce leaks when not in use. The design is intended for quick, one-handed sipping during activities without fully removing the lid. While not a substitute for a sealed travel mug when inverted for long periods, the lid minimizes accidental drips and streamlines mid-activity hydration.

• Flip-up straw for hands-free sipping.
• Snap-shut mechanism to block stray spills.
• Large opening for faster flow and easy cleaning.
• Designed for stability during movement, like driving or walking.

Will this tumbler keep drinks cold on long days?

Yes—the Quencher uses double-wall vacuum insulation to slow heat transfer and maintain cold temperatures for hours. Its stainless-steel construction and insulated chamber reduce ice melt and help beverages stay refreshing through a full day of errands or exercise. Insulation performance varies with ambient temperature and how often the lid is opened.

• Double-wall vacuum insulation for extended chill.
• 18/8 recycled stainless steel resists temperature change.
• Wide opening allows ice cubes and fast refills.
• Recommended to pre-chill for maximum cold retention.

Is the Quencher durable and easy to maintain?

The tumbler is built from durable 18/8 recycled stainless steel and is BPA-free, delivering both longevity and safer contact with liquids. It is dishwasher-safe for convenience, though hand-washing the lid parts can help preserve seals and moving components. The textured handle and rugged finish stand up to daily use, travel, and outdoor activities.

• 18/8 recycled stainless steel body for long-lasting durability.
• BPA-free materials for drink-safe use.
• Dishwasher-safe body; recommended gentle cleaning for lid pieces.
• Textured handle resists slipping and improves grip.

Does this tumbler fit in my car and carry comfortably?

The Quencher is sized with a tapered base to fit most car cup holders while its textured comfort-grip handle makes carrying a full 40 oz load easier. The handle provides leverage for pick-up and transport, and the narrow base means it won’t dominate the center console. Keep in mind that fit can vary by vehicle and aftermarket cup-holder sizes.

• Tapered base fits most standard car cup holders.
• Comfort-grip handle designed for easy lifting and carrying.
• 40 oz capacity reduces the need for frequent refills.
• Two-tone lid and soft-texture handle add ergonomic style.

Who is this for? The STANLEY Quencher ProTour Flipstraw Tumbler (40 oz) is aimed at people who want a large-capacity, sturdy travel cup that keeps beverages cold and lets them sip quickly while on the move. It’s a good match for commuters, outdoor enthusiasts, gym-goers, parents managing busy days, and anyone who prefers one-handed sipping without sacrificing insulation or durability. If you need a compact, spill-proof bottle for extended outings or all-day desk use, this Quencher blends capacity, grip, and leak-reducing convenience into a single, reusable tumbler.
