Most people associate Stanley with the viral Quencher tumbler – the one you see everywhere, from gym bags to office desks. But what many don’t realize is that Stanley offers a wide range of tumblers, each designed with slightly different use cases in mind.
In this guide, we’ll break down the three models people are obsessing over right now: the Quencher, ProTour, and IceFlow. By the end, you’ll know exactly which one fits your lifestyle best.
Before we start, keep in mind that the tumblers themselves are surprisingly similar. They all deliver excellent insulation, durability, and that signature premium feel. The real difference? The lids. And that single detail has a huge impact on how practical, versatile, and convenient each tumbler is in everyday use.
Let’s take a closer look at what sets them apart.

3rd place: Stanley Quencher
It might sound surprising that the viral Quencher, the tumbler influencers seem to love, lands in last place in my ranking. But honestly, I think it’s a bit overhyped, and I wouldn’t recommend it as your first Stanley.
My biggest issue with it is simple: it’s NOT leakproof. The Quencher comes with the FlowState lid, which leaks. Yes, there’s a rotating tab, and yes, you can remove the straw and cover the opening, but even then it doesn’t seal properly.
If the cup tips over, water will still find its way out. At best, it’s splash-resistant. It’s not something you can confidently throw into a bag and forget about. You always have to keep it upright, which gets annoying fast.
I’m also not a big fan of the handle. It looks nice and trendy, but in practice it’s not that comfortable, especially when the tumbler is full. It starts to feel bulky after a while. You can hold it by the cup itself, but most Quenchers have a smooth finish without much grip. If your hands are wet, it can easily slip, which isn’t ideal.
To be fair, the Quencher works fine in more stationary situations. It’s great for your desk or the car, and like most Stanley tumblers, it fits well in standard cup holders (aside from the massive 64 oz version).
One thing it does really well is handling hot drinks. The FlowState lid doesn’t build up pressure, so you can safely use it for coffee or tea. That’s usually when I reach for it.
If you’re considering it anyway, I’d recommend reading a more detailed Stanley Quencher review to understand its pros and limitations before buying.
Still, despite all the hype, I think the ProTour and IceFlow are simply better choices overall, even if they don’t get nearly as much attention.
2nd place: Stanley ProTour
The ProTour fixes the biggest issue I have with the Quencher because it’s actually leakproof. The lid uses a straw spout that’s comfortable to drink from, and there’s a small tab you can push with your thumb, so you don’t have to touch the mouthpiece with your fingers. It feels a lot more hygienic compared to some other tumblers I’ve used.
When you’re done drinking, you just push the spout down until it clicks into place. Once it’s sealed, you don’t have to worry about leaks. Like with any straw lid, you do need to make sure it’s properly closed, but it’s not something that bothered me in everyday use.
That said, it’s not perfect. I wouldn’t use it with hot liquids because pressure can build up inside the lid. Warm drinks are fine, but anything really hot feels a bit risky. And just like the Quencher, you’re limited to carrying it by the handle, which can get uncomfortable after a while, especially when it’s full.
Even with those downsides, I still like the ProTour a lot. I find myself reaching for it more often than the Quencher.
1st place: Stanley IceFlow
The IceFlow is my favorite Stanley tumbler. To me, it feels like an upgraded version of both the Quencher and the ProTour.
First of all, it’s completely leakproof. If you think you don’t need that, I used to think the same. I bought the Quencher and after about a month I replaced it with the IceFlow for that exact reason. Not having to worry about spills makes a bigger difference than you expect.
Now, the ProTour is also leakproof, so why do I still prefer the IceFlow? It mostly comes down to the lid. The ProTour lid is good, but it feels a bit thinner and less solid. The IceFlow lid, on the other hand, feels sturdier and more durable. It also screws on and off more smoothly.
The biggest advantage, though, is the handle. Instead of a large side handle, the IceFlow has a bucket-style handle attached to the lid. It’s comfortable, well-shaped, and easy to grip with all your fingers. That alone makes it much more practical to carry around. I’ve taken it on walks, quick trips outside, even short hikes, and it just works.
Of course, this comes down to personal preference, but I’ll take this kind of handle over a side handle any day, not just on Stanley tumblers but on bottles in general.
Overall, the IceFlow feels like the most versatile option. You can take it almost anywhere without thinking twice. The only downside is the weight. Like most Stanley tumblers, it’s not light. My 30 oz version weighs close to 20 oz when empty, which you do feel after carrying it for a while.
Pro Tip: Stanley Lids Are Interchangeable
One thing worth knowing is that Stanley lids are interchangeable, as long as you’re using the same cup size. That means you can mix and match between the Quencher, ProTour, and IceFlow depending on what you need.
The catch is that Stanley only officially sells the FlowState lid on its own, usually for around $8 to $10. The other lids aren’t available separately through Stanley. You can find third-party options online that claim to be compatible, but I’d be a bit careful with those since they’re not official.
If I had to give one simple piece of advice, it would be this: go with the IceFlow, then pick up a FlowState lid separately if you want more flexibility. That way, you get a fully leakproof tumbler for everyday use, plus the option to switch lids when you want to drink hot coffee or tea without worrying about pressure building up.
It’s a simple setup, but it gives you the best of both worlds.
Finally, if you’re still unsure which capacity is right for you, it’s worth checking this guide on Stanley tumbler sizes before choosing a model. And if you’re comparing Stanley to other brands, you might also want to check this list of the best tumblers to see how it stacks up.
