STANLEY Quencher ProTour Flipstraw Tumbler 30 oz Pistachio — Leak-Resistant, Insulated Cold-Only

The STANLEY Quencher ProTour Flipstraw Tumbler (30 oz, Pistachio) is a leak-resistant, double-wall vacuum insulated cold-only tumbler with a flip-up straw and a comfortable textured handle for all-day chilled hydration.

This 30-ounce Quencher from STANLEY blends durable recycled 18/8 stainless steel construction with a user-friendly Flipstraw lid and a narrow base designed to fit most cup holders. Built for cold beverages only, the Pistachio finish adds a modern, fresh look to the brand’s classic rugged design. Its dishwasher-safe parts and thoughtful details—like the soft-grip handle and two-tone lid—make it a practical option for daily commutes, workouts, and outdoor activities where keeping drinks cold matters.

How does the Flipstraw lid prevent spills while letting me sip easily?

The Flipstraw lid has a hinged drinking spout that flips up for drinking and snaps closed to help block spills. When assembled correctly—with the straw and drink spout in place—the lid creates a seal designed to minimize leaks during normal use. It’s important to ensure all pieces are tightened fully and to avoid overfilling the cup to maintain leak resistance.

• Flip-up straw for quick, one-handed sipping
• Snap-shut spout reduces accidental spills when closed
• Designed to be leakproof when assembled and closed properly
• Not recommended for carbonated or hot beverages

How long will drinks stay cold in the 30 oz STANLEY Quencher?

The Quencher uses double-wall vacuum insulation to slow heat transfer and keep cold drinks chilled for hours. While exact cooling time varies with starting temperature and ambient conditions, the insulated walls are effective for long workdays, gym sessions, and outings. Avoid freezing or using hot liquids, as the product is built specifically for cold use and different temperatures can affect performance.

• Double-wall vacuum insulation preserves cold temperatures
• Suitable for extended outings and daily hydration
• Avoid freezing or hot liquids to protect insulation and lid integrity
• 18/8 recycled stainless steel construction resists corrosion

Is the Quencher easy to clean and maintain?

The tumbler and lid are dishwasher-safe, though hand washing can better preserve painted finishes and reduce wear over time. For stubborn stains, soak the tumbler overnight in warm water with baking soda—remove the lid while soaking to prevent pressure buildup. Avoid strong chlorine or bleach detergents and commercial high-heat dishwashers to protect the vacuum seal and finish.

• Dishwasher safe for convenient cleaning
• Hand wash recommended to preserve painted surfaces
• Soak with warm water and baking soda to lift stains
• Avoid bleach or high-chlorine detergents and commercial dishwashers
