Unless you live under a rock — or don’t have an Instagram account — you’re probably familiar with Stanley’s most popular Adventure Quencher Travel Tumblers. The top choice of countless influencers, Adventure Quencher was launched in 2016 by Stanley, a 109-year-old brand known for its camping gear and outdoor accessories.
Though an unlikely duo, Stanley and the content creator have now become a recipe for success that other brands are desperately trying to emulate: These days, as influencers urge their massive followings to buy their brand within minutes of a second purchase, Its sold out it becomes available. Not only has Adventure Quencher amassed a waitlist of over 150,000 people since its inception, but #stanleytumbler has over 25 million views on TikTok.
As an early adopter of Adventure Quencher, I’m here to say that all the hype is actually worth it. As a product tester, I receive everything from leggings and sports bras to toasters and water bottles. A few years ago, in the sea of swag on my dinner table, the Stanley Cup not only stood out and piqued my interest, but it quickly became my everyday item.
Currently in stock on Amazon in several colors, the Adventure Quencher is also in the news as it just got a new and improved sister mug called the Quencher H2.0 Flowstate Tumbler which just launched today featuring a new soft Matte finish. Given my love for the original, I had to try Stanley’s latest version and (spoiler alert) it’s really good. that’s why.

It’s hard to improve on something this good, but Stanley did it with the Quencher H2.0 Flowstate while managing to keep the price exactly the same ($20 to $45). With a little tailoring, small changes can make a big difference.

What makes a mug so great? Well, for one thing, it’s huge. Sure, it comes in 14 oz, 20 oz, and 30 oz, but everyone who knows the Stanley secret knows that the 40 oz – with its reliable built-in handle – is the sweet spot.
And that intense pressure also helps keep me extremely hydrated. Anyway, I’m a super thirsty person, but the huge size of the Adventure Quencher allows for less time refilling and more time drinking. If I only supplement twice a day, I’m close to the 92 ounces per day recommended by the National Academies of Sciences, Engineering, and Medicine. The mug’s double-wall insulation also keeps drinks hot for seven hours and chilled for two full days—seriously, the ice cubes stay intact for 48 hours.
Another detail I like is that, despite its size, the Adventure Quencher has a tapered, slim base that fits in my car’s cup holder. This is a big deal to me (and all the suburban moms out there who love it) as I spend a dozen hours a week in the car, driving my kids around and having to have all the necessities (including water) . MORE INFO: If you’re not a straw fan, don’t worry – the mug has a twist-off lid that allows three positions: straw, spout, or full lid closed (more on that below).
There’s also the hype factor. If you think about it, it’s a simple equation. Everyone Wants Adventure Quencher and Really hard to come by. When I’m running errands or sitting on the sidelines of a football field, strangers often come to me and ask me if a) the mug is as good as people say it is, and b) how I got one. The gist is this: people notice the mug, they want to talk about it, and subsequently, they want one too. All the lovely colorways—from neutral cream to bubblegum pink—make the mugs perfect for ‘grams, too. Oh, not to mention it can go in the bottom rack of the dishwasher at the end of the day. (Although, full disclosure, I keep mine next to my bed for a midnight hydration!)

It’s hard to improve on something this good, but Stanley did it with the Quencher H2.0 Flowstate while managing to keep the price exactly the same ($20 to $45). With a little tailoring, small changes can make a big difference.
For example, that handle I mentioned earlier was a key part of the success of the original Adventure Quencher—it was ergonomically designed and made carrying a large mug a breeze—while the Quencher H2.0 has a new two-tone “comfort grip” that Arranged in processing. Is this a necessary detail? No. do i like it Absolutely. Not only does it look great, but it feels luxurious and helps me get a better grip on the handle. Oh, and the 30 oz size of the Quencher H2.0 comes with a handle, while the Adventure Quencher 30 oz does not.
The straw on the Quencher H2.0 has also been upgraded with a new silicone seal that wraps around the base of the straw and is designed to prevent spills. Full disclosure: If you knock over the Adventure Quencher, water will flood the floor. This new “splashproof” detail isn’t completely waterproof, but it certainly slows down spills, as good as you get with a sippy cup.
While this detail isn’t visible to the naked eye, I’m a big fan of Stanley’s commitment to sustainability, which is at the heart of the Quencher H2.0 – the mug is made from 90% recycled stainless steel.
What We Don’t Like About the Adventure Quencher and Quencher H2.0 Flowstate Glasses

When it comes to this mug, there’s nothing to be mad about. If I had to choose something, I’d pick both Quencher cups are not spill-resistant, which makes it unsuitable for long trips. For example, you can’t toss a mug into your handbag like you can a sealed water bottle.When traveling this summer, I didn’t have my beloved Adventure Quencher and ended up drinking Way Less Water When you’re out of town, it’s rare that you miss a glass a day, but that’s exactly where I am.

I’ve tried a lot of mugs and water bottles over the years, and Quenchers are hands down my favorite, even over spill-proof bottles, mainly because the Stanley mug’s straw design makes it super easy to drink on the go, while water bottles require unscrewing the bottle Cap or flip the spout – sure, it only takes a second, but it adds a prep step to every sip I drink.
Compared to other mugs with straws, the Stanley tumbler definitely wins in terms of quality and design. The Reduce 40-ounce Cold1 Insulated Stainless Steel Straw Cup is a fan favorite at Target, and it has a nice straw lid and a cheaper $25 price tag, but it doesn’t fit in standard cup holders, and while promising it keeps water cold for 34 hours, for hours Then I found out that the ice had melted.
I’m a big fan of Yeti’s coolers, chairs, etc., but the Rambler 25 oz stackable mugs are also inferior to Quenchers due to the absence of handles – making carrying things cumbersome and laborious when I’m holding things with both hands! – and a crude lid that only holds one straw. (Editor’s note: Yeti recently launched a new Rambler mug in 25-ounce and 35-ounce capacities with handles. ) If you want a spout/lock lid, you’ll have to spend an extra $10 for the brand’s most popular Magslider lid.
You can’t go wrong with either the Stanley Adventure Quencher Travel tumbler or the newer Stanley Quencher H2.0 Flowstate tumbler, but if I were forced to choose, I’d go with the new and improved Quencher H2.0 Flowstate. The sealed straw spout and silicone-lined handle have me hooked, and the recyclable nature of the mug makes it a feel-good, eco-friendly option.
