STANLEYQuencher ProTour Flip Straw Tumbler with Leakproof Lid | Built-In Straw & Handle | Cupholder Compatible for Travel | Insulated Stainless Steel Cup | BPA-Free

I’m genuinely impressed by the Stanley Quencher ProTour Tumbler. The vivid violet fade is absolutely stunning—eye-catching without being over the top. The flip straw lid is a game-changer: it’s truly leakproof, making it perfect for tossing into my bag without worry. I love how the double-wall insulation keeps my drinks ice-cold for hours, even in the Caribbean heat! The comfort-grip handle and cup-holder-friendly base make it super convenient for travel, work, or workouts. Plus, knowing it’s made from recycled stainless steel and BPA-free materials adds peace of mind. Durable, functional, and beautiful—this tumbler checks every box.

The best cup I’ve ever had!Living in the Las Vegas summer heat, this cup is essential. It holds just under a liter, which is perfect for 20–30 minute outings without constantly running out of water (I used to have a 24 oz and always ran out). It’s very sturdy, doesn’t leak even when flipped, and the design is great—it fits perfectly in my cup holder and keeps water cold for hours, even in 100+ degree weather. Highly recommend!

I love the color. Standley cups work very well with keeping drinks hot or cold. Lid is lid works well and does not leak . Sturdy and does not leak. Perfect to take anywhere. I use it to keep my water cold in the summer. Not sure about the brewing capacity I sure it is fine.

The Stanley 40 ounce in the dried pine is the best water bottle I’ve ever owned and I’ve had a ton. It is truly leak proof. It keeps water cold all day which is my biggest need in water. The color is awesome. Took me a long time to pull the trigger on it because I was skeptical about getting the water bottle that is a fad but this thing was 100% worth it. Would absolutely buy again.

I finally caved and got a Stanley cup, and I am obsessed! It keeps my drinks ice-cold for hours (seriously—overnight!), and I love how much water I drink now just because I want to carry this around everywhere. The handle is sturdy and super comfortable to hold, and the design fits perfectly in my car’s cup holder, which is a major bonus.The quality feels top-notch, and it’s surprisingly easy to clean. I also love all the cute color options—mine is gorgeous and gets compliments all the time. If you’re on the fence, just go for it. Totally lives up to the hype!

I had the original quencher and always poured staff in my car, since getting this, I love it! love the size, it gives me a liter and a bit more of water each time, looks great, easy to clean and keep my tea hot for hours! I have had my old quencher for two years and it still works fine. I now swap covers between this and the old.

This is my first Stanley cup. It is worth all the hype. Doesn’t stay cold for as long as it claims. Well it won’t be hot but not as cold as it started. I like having 40ozs to take with me on these hot days. The handle and base provides for great stability. NO DRIPPING! The cup can even be hard to open at times. Having fun with accessories. Really making it my own.

Extremely happy with purchase and impressed on hold time with ice in it. Love the flip straw and it doesn’t leak as specified. Great color options. Wish they can have us be able to design our own stuff like other brands.
