 Which Stanley IceFlow is Better? How is Stanley's IceFlow 2.0 Different from the Original, and Is It Actually Better?These two Stanley IceFlow tumblers look almost identical, but one is highly recommended and the other is a bottle you should avoid like the plague. This post will run through the differences that actually matter, as well as show you what to look for in the Amazon listings to make sure you get the right one. And you'll want to read that part because as of right now the Amazon listings are kind of a jumbled mess, so it's easy to accidentally buy the older IceFlow 1.0. Let's get going! What's Next?

Part 1: What's Similar and Difference between Stanley's IceFlow 1.0 and 2.0? Stanley IceFlow 1.0 (left) and 2.0 (right) At first glance, these two bottles look almost identical (at least practically, not judging by color). They both have:
But look a little closer, and you'll notice several changes that make a big difference. Spoiler alert...they're good changes! Change #1: Removable Spout and Seal With the original, the spout was not removable. Yes you could pop it out like I did (evidence below), but it's really difficult and will probably lead to damage. The thing is, these types of straw bottles with flip-up spouts are notorious for hiding mold, germs, and bacteria because there's always a seal that you can't really effectively clean because the spout is in the way.  Stanley IceFlow 1.0 has a Non-Removable Spout Stanley solved this problem by making the Stanley 2.0 IceFlow with a removable spout. To remove it, you raise the spout up about 45 degrees, then pull it out at that angle. It might take a little effort, especially with a brand new bottle, but it's pretty easy to do.  Stanley IceFlow 2.0 has a Removable Spout Change #2: Removable Seal Under the Flip-Up Spout Because the spout is removable, it's also easier to get to the seal under it. Stanley also updated the seal design so it's easier to take out for cleaning.  Stanley IceFlow 2.0 has a Removable Seal The removable spout is easier to snap back into place than it is to remove. However, the removable seal is a little more difficult to get back into place because of how flexible the material is and how you have to force it into the hole. A trick is to use the straw to help ease it into place. Change #3: How Easily the Spout Rotates and "Locks" With the original IceFlow, the spout rotates smoothly all the way between open and closed. The spout doesn't "snap" into place, and it's kept closed primarily with a friction fit. This also means the spout requires more force to rotate it open and closed. Notice the lack of any notches on the side of the spout below.  Stanley IceFlow 1.0 (no notches on the side of the spout) With the 2.0 IceFlow, Stanley added these little notches on either side of the spout, and the lid has corresponding bumps. What this does is it adds a little more resistence on that last little bit of the rotation, and then it snaps into place when fully closed. That physical feedback is both helpful to know that it's actually fully closed, and it also helps prevent the spout from accidentally opening, which can be a problem if you have your bottle in a bag or purse.  Stanley IceFlow 2.0 (has notches on the side of the spout) 2.0 also rotates with less resistance until you get to that closing position. Compare that to the original that has a consistent tighter fit over the whole rotation, making it so you need to use a little more force to rotate it. Which One is Better? Overall, these three changes are the main practical updates to Stanley's IceFlow tumbler, and they make the 2.0 version a much better bottle overall compared to the original. Part 2: Are Stanley's IceFlow 1.0 and 2.0 Bottles and Lids Interchangeable?A couple other minor differences are the the 2.0 straw is slightly larger, and you can really see that here because the version 1 fits inside the version 2 straw.  Stanley IceFlow 2.0 has a Larger Straw Also, the thread design is a little different, and 1.0 needs about 2/3rd of a rotation to open while 2.0 just needs about 1/3rd.  Stanley IceFlow 2.0 has Coarser Threads These aren't huge differences, but I wanted to mention them so you know the lids and bottles are not interchangeable. You can't put a version 1 lid on a version 2 bottle and vice versa. Part 3: How to Find the Correct Stanley IceFlow on AmazonIf you're shopping on Amazon, it can be difficult to know which version you're looking at because they're so similar. I think part of this is because 2.0 is so new, and Stanley is probably in the middle of transitioning their Amazon listings to the clearly better 2.0. So here's what to look out for to make sure you buy the correct one. You'll know you're on the main Stanley IceFlow listing if it has at least 60,000 reviews, and you'll see all the possible color combinations. Most of these are the new 2.0 version, but some are the older design so you need to look closely. To find out which ones are which, there are four main places to check.
First, look for the lid closeup picture, and make sure it has wider notches on either side of the spout. These notches are only with the 2.0 tumbler because that's what makes the spout removable.  Stanley IceFlow 2.0 has Wider Notches on the Sides of the Spout Second, you can also check this first bullet point to see if it says Flip Straw 2.0.  Stanley IceFlow 2.0 Listing (1st Bullet Point) Third, you can check the fifth bullet point to see if it mentions a removable spout and seal.  Stanley IceFlow 2.0 Listing (5th Bullet Point) And fourth, there are some other listings like this one that clearly indicate it's a 2.0 IceFlow in the actual title of the listing, so that's an even safer bet.  Stanley IceFlow 2.0 Listing (Title) Just a heads up, it's not very consistent. For example, some 2.0 listings don't mention the removable spout and seal on the fifth bullet point, but they mention the new lid on the first one and the lid closeup picture shows the wider notches.
Also, this is a snapshot of today, so don't be surprised if things change in the future. It's all a little confusing since Stanley seems to be updating their listings, so it helps to check each of these places on the listings. Hope this helps, and happy hydrating!
