STANLEY Quencher ProTour Flipstraw Tumbler — 40 oz Blue Sky, Insulated Leakproof Travel Cup

The STANLEY Quencher ProTour Flipstraw Tumbler is a 40 oz insulated, leakproof travel cup with a flip-up straw, comfort handle, and double-wall vacuum insulation to keep drinks cold for hours.

The Quencher ProTour marries rugged Stanley durability with a user-friendly flip straw lid that snaps closed to prevent spills. Crafted from 18/8 recycled stainless steel and finished in the Blue Sky colorway, this 40 oz tumbler was designed for long days, road trips, gym sessions, and everyday hydration. It fits most car cup holders, offers a textured comfort-grip handle, and is dishwasher-safe for easy cleaning.

How does the flip-straw lid prevent spills during travel?

The ProTour Flip Straw lid has a built-in straw that flips up for sipping and snaps down to seal the opening when not in use. The mechanism reduces accidental spills while you move or stow the cup in a bag, and the lid seals securely to limit leaks.

• Flip-up straw for one-handed sipping
• Snap-shut closure to block the straw opening
• Leak-resistant construction designed for commuting and travel
• Two-tone lid for clear open/closed orientation

How long will drinks stay cold in this 40 oz tumbler?

Double-wall vacuum insulation keeps beverages chilled far longer than a single-walled cup. While exact times depend on starting temperature and ambient heat, the Quencher ProTour is engineered to maintain cold temperatures through a typical workday or outdoor activity.

• 18/8 recycled stainless steel for thermal efficiency
• Double-wall vacuum barrier reduces heat transfer
• Large 40 oz capacity minimizes refills during long outings
• Metal interior preserves flavor without plastic taste

Is this Stanley Quencher easy to carry and clean?

The textured handle gives a secure, comfortable grip, and the tumbler’s narrow base fits most car cup holders for easy stowage. The stainless-steel body and removable lid components are dishwasher-safe, simplifying post-use cleanup.

• Comfort-grip handle for steady carrying
• Narrow base designed for standard cup holders
• Dishwasher-safe parts for low-maintenance care
• BPA-free materials for safer sipping
