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!

This Stanley cup is pure excellence. The build quality is outstanding — sturdy, sleek, and designed to last. It keeps my water ice-cold for hours, even in the summer heat, and the straw + handle combo makes it super convenient to carry everywhere.I find myself drinking way more water just because I actually want to use it. It fits in my car cupholder, doesn’t leak, and somehow still looks brand new after daily use.If you’re on the fence — get it. Totally worth the hype and one of the best purchases I’ve made for staying hydrated!

It feels solid and I do really love the colors they have, I havnt had or seen any leaks and it’s held ice in my work truck when it’s been more then 100 degrees inside the truck. I’m pleased with the cup, I had off brands before as I’ve never had the money to buy a name brand but I decided to give it a shot and I’m happy with the purchase. Plus it comes with a lifetime warranty.

I finally got my Stanley cup and it’s amazing! It keeps my drinks cold for hours — sometimes even overnight. I love how sturdy and stylish it is. The handle makes it super easy to carry, and the straw is perfect for sipping on the go. It fits in my car cup holder too, which is a big plus. If you’re looking for a reliable tumbler that actually keeps drinks cold, this is worth every penny!

Perfect size, keeps cold and let’s not get started on the color! I love it.This design is much better as it doesn’t leak and takes apart fully for efficient cleaning.

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.

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.
