STANLEY Quencher ProTour 40 oz Flipstraw Tumbler — Hydrangea, Leak-Resistant Insulated Cold Cup with Handle

The STANLEY Quencher ProTour Flipstraw Tumbler in 40 oz Hydrangea is a leak-resistant, double-wall vacuum-insulated cold-only travel cup with a flip straw and comfort-grip handle for all-day chilled hydration.

This 40-ounce Quencher from STANLEY combines rugged stainless-steel construction with a user-friendly Flipstraw lid, designed specifically for cold beverages. Finished in a soft hydrangea tone, it balances style and function: a slim base for cup holders, textured handle for carrying, and a straw lid that snaps closed to help prevent spills. It’s built from 18/8 recycled stainless steel and is BPA-free, dishwasher-safe, and intended for cold-use scenarios only.

How does the Flipstraw lid prevent spills during daily use?

The Flipstraw lid is engineered to snap down over the straw to reduce accidental flow when not drinking, helping contain minor tilts and bumps. It’s easy to open with one hand and seals when closed, offering a convenient balance of accessibility and spill resistance.

• Flip-open straw for quick sips, single-handed operation
• Snap-shut design to limit accidental flow and small leaks
• Assembly guidance ensures full leak-proof performance

How long will drinks stay cold in the 40 oz Quencher?

Double-wall vacuum insulation keeps cold drinks chilled for hours, so water, iced coffee or other cold beverages stay refreshingly cool through a long workday or outdoor activity. Insulation performance depends on starting temperature and ambient conditions.

• Double-wall vacuum construction reduces heat transfer
• Maintains ice-cold temperatures much longer than single-wall cups
• Best results when pre-chilled or filled with ice

What cleaning and maintenance does this tumbler require?

The tumbler and lid are dishwasher-safe under normal household settings, but hand washing preserves paint and finish longer. Avoid commercial-strength dishwashers and harsh chlorine detergents; for stubborn stains, a warm baking soda soak overnight works well.

• Dishwasher-safe on household cycles; avoid high-heat commercial washers
• Hand wash recommended to protect painted finishes and artwork
• Soak with warm water and baking soda to remove tough stains

Who should choose the 40 oz Hydrangea Quencher ProTour?

This tumbler suits commuters, students, outdoor enthusiasts, and anyone who prefers a large-capacity cold beverage container with a comfortable handle and a spill-reducing straw lid. It’s ideal for long days when carrying a lot of water or iced drinks is necessary, and for users who want a durable, reusable alternative to disposable cups.

Before use, follow safety guidance: this product is intended for cold beverages only and is not for carbonated, citrus, fermenting, hot, milk-based, or baby-food contents. Assemble the lid, drink spout, and straw correctly to ensure leak-proof performance, and do not overfill. Avoid microwaving or freezing the tumbler to preserve function and finish.
