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

I love the color, its unique, no leakage and water stays cold all day. Lid does its job, no leak. Easy to clean and use. Holds a lot of water and easy to use. Durable and functional. Overall great for travel.

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’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.

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.

I loved the first one I got so much that I bought another one! The 30oz perfectly fits in my cupholders, and I love the straw top/sippy cup thing so it’s 100% leakproof! It’s really light weight, easy to carry and is my favorite stanley to take on the go. Not to mention I live in Texas so the fact that ice can stay frozen for 12+ hours is insane! Dishwasher safe also makes it worth the money, and it’s sturdy enough to stay shiny and insulated after tons of washes!

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 love the look and function of my Stanley cup overall — it keeps drinks cold for hours, fits in my car’s cupholder, and holds a ton of water, which helps me actually stay hydrated throughout the day. The handle is sturdy and comfortable, and I like that the design is sleek but still practical.That said, I opted for the flip straw lid version and have mixed feelings. It’s convenient and less spill-prone than the open-top style, but the flip piece doesn’t always stay closed as tightly as I’d like. I haven’t had a full spill, but if it tips over in a bag or on the passenger seat, you might get a few drips. Also, the straw can be a little harder to clean compared to some of the other water bottles I’ve owned. Overall, I still use it daily and love it but I’d say the flip lid is best for upright use only. If you need something totally leakproof, maybe go with a different lid.

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!
