STANLEY IceFlow 2.0 Flip Straw Tumbler, 30 oz, Sienna

I absolutely love this Stanley tumbler! The color is even more beautiful in person, and the quality is exactly what I expected. It's sturdy, easy to carry, and fits perfectly in my car's cup holder. The Flip Straw lid is super convenient and truly leakproof, so I can toss it in my bag without worrying about spills. It keeps my water cold for hours, even on hot days. It's easy to clean, comfortable to hold, and perfect for everyday use. If you're looking for a high-quality tumbler that looks great and performs even better, I highly recommend it!

This Stanley IceFlow water bottle is the perfect size for me. Very easy to grab from the handle. It feels solid and stable. The lid screws on, and the straw and sip hole are oversized, so easy to drink from. I didn't think it was keeping cold as long as it should, but then I tried putting cold water in it before mixing my drink. Letting it sit and get the inside cold. Then dump, fill with ice and water and my drink mix and now the ice stays all day. This fits in my car cupholder easily. It doesn't leak. Easy to mix my drink mix by shaking it. No leaks. Well made, easy to use. Love the color!

I really love this Stanley cup! It keeps my drinks cold for hours, the handle makes it easy to carry, and it fits perfectly in my car’s cup holder. It’s sturdy, easy to clean, and has become my favorite tumbler. Definitely worth buying!

This is my second Stanley; I believe the hype. I've been using it every day for work, errands, and the gym, and it's become something I never leave home without. My drinks stay cold all day, even had ice in it the next day. Keeping it close has helped me drink a lot more water throughout the day. So comfortable to carry, and despite the size, it fits perfectly in my car's cup holder. The reusable straw makes sipping convenient while I'm on the go.

I waited a full week before writing this review, to test this and live with it a bit. I'd read so many reviews of different products of this Type- Including YETI, HydroFlask, etc. About 20 months ago, I'd bought a few Zojirushi water bottles as stocking stuffers for my wife and I- having already been-through a few other brands and types that ultimately didn't gain favor or last. And sadly, the Zojirushi though well-rated was similarly destined to replacement for various reasons I won't list here, but it was loud in its operation (think you want a quiet drink at 3am without waking your significant other, nope) and didn't "drink from" well, if that makes sense. Yeti- I was set to spring for them....but meh. More "Brand/Status identity" than actual performance & substance IMO...and overpriced because of that. And so forth. I am truly a buy-once, cry-once person; but I also understand VALUE. It's not always 'the most expensive' that is the best...and this Water Tumbler is a prime example of that. Ladies and Gentlemen, I introduce the Stanley IceFlow 2.0 Flip straw number. I've finally found the right water tumbler. Made by STANLEY- industry standard for years and I know it's more a utilitarian "brand" and not fashionable, but IT DELIVERS... and I could not be more exuberant over such a simple item. It handles well, travels well, & for me, the 30oz is just the sight size for overall day to day travel and errands, it hasn't leaked, temperature retention is EXCELLENT and it's well-made. I like the carry handle which tilts out of the way, but is robust enough for daily use without the concern over it breaking due to cheap manufacturing. And in its function- it's QUIET!!!! Flip the flip-straw spigot up and it quietly does so and just a quietly flips back into its sealed position. No waking the spouse at 3am with a click-click or other obnoxious noises that seemingly are amplified in the wee quiet hours of sleep time. This is important for me/us. lol I wasn't sure I'd like the straw-oriented setup, and I absolutely LOVE IT. Simple to manipulate the spigot, even when driving, if need be. The straw removes easy for easy cleaning, the entire tumbles is easily cleaned ( I hand-wash mine only) but it's dishwasher safe, BPA-Free (!!), and the size of the straw allows you to draw a good volume of water. And quietly. Now the finish- first, I chose the ASH color so as to not draw heat like darker colors will, and shows less handling smudges or gunk. BUT THE TEXTURE IS DA-BOMB!!! It's perfect for traction/grip, but not too coarse to draw unwanted oils and dirt AND it seems to be resistant to mars & scratches. I had an armful of shopping bags a few days ago and my car keys and gripping the side of the tumbler (not the handle in this instance) in the other hand, as my wife and I came home from the grocery store- and I'm thinking "okay those car-key edges are chafing the side of the mug and I'll probably have scratches on it"....not a single one. Nothing. So robust. Now I'm sure if I were to kick it down a gravel driveway that might be a different story, but you get the idea. The finish & material overall, is QUALITY. I'm seriously thinking of getting one or two more of these in different colors just for the "mood" that I may be in at the moment...lol, but honestly, this simple water tumbler has been the most surprising Amazon purchase I've made in a long time...maybe THE most. UPDATE 8/16/26: I put a handful of ice cubes into this tumbler last night before bed and filled it with water. As of right at at 6pm the following evening, the water in the tumbler is still cold enough to give you a brain freeze. Seriously. If that's not well-insulated, I don't know what is. (end of update) THIS IS AN EPIC WIN, and a must-have.

This water bottle is so ideal! We have a few of the 20oz bottles for my kids but my oldest needed a larger one for Forest school. The large handle makes carrying a breeze and the fact that it’s leakproof and can fit in a cup holder is huge. The color options are wonderful! I know it will last a long time.

I got this tumbler for my son to take to school, and it has turned out to be a really practical choice for everyday use. The 30 oz size is just right for a full school day. It holds enough water so he doesn’t have to constantly refill it, but it’s still manageable for him to carry in his backpack or by the handle. For a kid who is always running between classes and activities, that balance really matters. One thing he immediately liked was the color. The Blue Sky shade is bright, cheerful, and easy to spot. Kids misplace things all the time, but this one actually stands out enough that it’s easy for him to recognize it among other bottles. That small detail has surprisingly helped prevent it from getting lost. The flip-up straw design is also very convenient. He can quickly take a sip without needing to unscrew anything, which makes it easy during short breaks at school. The straw pops up smoothly and closes securely, and it hasn’t leaked in his backpack so far, which was one of my biggest concerns when choosing a bottle for school use. The handle makes a big difference too. It’s comfortable for him to carry when his backpack is already full, and it also makes it easy for him to grab it quickly when heading out the door in the morning. Kids don’t always think about convenience, but this design clearly works well for them. Another thing I appreciate is the insulated stainless steel body. His water stays cool for a long time, even through a full day of school. By the time he gets home there’s often still cold water inside, which encourages him to drink more during the day. Overall, this tumbler feels sturdy, practical, and very kid-friendly. My son genuinely enjoys using it, which honestly makes a big difference when it comes to getting kids to drink enough water. The size, color, handle, and easy straw design all work together really well, and it has been a great everyday water bottle for school. I would absolutely recommend it for kids or anyone who wants a reliable insulated tumbler that’s easy to carry and simple to use.

The STANLEY IceFlow 2.0 Flip Straw Tumbler is sturdy, convenient, easy to clean, and easy to carry. The flip straw makes drinking simple, while the insulated design helps keep drinks cold. Great for work, errands, workouts, or traveling
