I bought Thermos Ultimate 500ml and 900ml, they are both perfect. I will never buy any other. I create with them Tea and coffee on the go. Great heat retention!
I can't say that I'm surprised by the Yeti, they make pretty things for trendy people with too much money but the Sigg is a bit of a shock. It's nice to see that the Stanley is as good as I'd hoped it was when I bought one.
I support this test for no other reason than my choice of brand came out on top. I have had my thermos for about 9 years now and it has seen plenty of (not entirely but some arctic) abuse. It still keeps my liguids hot or cold for about 10 hours
If you know someone who uses a wheelchair, ask them to carry the water flasks for a day or two, I believe this will stand in for significant abuse over time. I recognize that a single data point is meaningless, but I'm going on 4 years with my clean canteen. There's not an undented square inch anywhere on it and it will not stand up anymore, yet the vacuum has not failed. I have replaced the cap once, not out of necessity, the loop broke. It does aggravate the hell out of me when companies purposely misspell things, I'm not much of a fan of logos in general. I'm happy to report that the clean canteen logo comes off very cleanly with a little bit of acetone.
I am surprised how long they keep the water warm. Seems like the cheap ones I own suck more than I thought they would suck :) Edit: it gets even worse. I just checked the prices of the ones in this video (can't remember if you mentioned the prices in the first video) and they really aren't that expensive.
I'm sort of surprised the yeti performed as well as it did. That company seemed to appear out of nowhere about a decade ago, I only ever see wildly enthusiastic users. Since consumers are morons, naturally I assumed some Kardashian used them and made them trendy. Trendy is always suspicious, it rarely tracks with quality. Just because it is mildly interesting and I don't know if it holds true in the UK, but almost every American associates the Stanley Thermos with Grandpa's pickup truck. It's mildly a cultural icon of masculinity, not unlike the Ron Swanson character. I thought that might help explain the weird passion people have for them.
I have the Thermos wich works increible, BUT the spout simeimes might be a bit anoing droping water when you're serving. Another big thing to consider, just i dropped the thermos 2 times from 20cm of altitude and i would say it's already not working anymore, it's losing a lot of temperature
i would like a test where you drop / toss the flasks off the top of alan into cold or freezing harbour water (obviusly attach a string to recover them) to see how they would fair in such a scenario and how much they would loose if submerged for a few hours, its something that can happen on an expedition, and even tho i dont explore much outside of some hiking trails, i like to keep a lanyard on my thermos for that (admittedly its more at risk of flying down a mountain than taking a swim in an ocean) very reason
Despite the undeniable theatre of such an event, I'm not sure that it would test the flasks too much, as the drop into water wouldn't cause damage, and water can't be very cold (although heat conduction would be a factor).
@@AlexHibbertOriginals well if the water does not do much damage, how about dropping em on a chunk of ice (or something of similar hardness) as that is still a scenario that can happen and will also cause damage
The stanley I have is more like the yeti with the screw top wide opening, do miss the cup sometimes since the coffee is often to hot to drink Happy to see some good testing.
One bonus for the Stanley is that the lids are interchangeable across a large range of models and have been for decades, so a spare can be grabbed from a kids lunchbox flask. Friend of mine is still using one that fell off the back of his motorcycle in the 90s. Other than scratching and the handle breaking off its still functioning great for his coffee.
there's no surprise if the flask, with the best performance overall, has a double sealed top, with the classic plastic top screw + mug. the design is unbeatable and wins in both thermos flask and thermos mug comparisons. And almost too often, the victory goes to Stanley or Thermos. or those who has a too good of a copy product ;)
TK Pro of Klean Kanteen >>>>> Thermos or Stanley. I prefer to sacrifice a couple of degrees of temperature in order not to have any type of plastic in the construction of the flask. When I drank coffee from a Thermos, its taste and smell were really disgusting (something that only happens in flasks with a plastic component). If you are not sensitive to plastic, it does not matter tho
Last year I bought a very expensive Stanley that boasted all sorts.....I sent it back after 2 weeks as it was just (and only just) like my cheapo from Tesco. I'm hoping my Thermos Ultimate 500ml is worth the money. Great testing though.
I mean durability is hard to test without real world trials. Realistically either the vacuum fails and or the rubber seals fail. I say drill a hole in the first layers of the flask to break the vacuum and cut the rubber seals, and then repeat the test, which bottle performs best at their worst.
Flasks all are each of their own. Yet brands like Yeti have always seemed to fail in many types of testings. This includes their over priced coolers. My 100 dollar Walmart Lifetime cooler for price is better than a Yeti. Project farm did a test about a year ago. ruclips.net/video/a6j1NJkNzwI/видео.html Its worth the watch to understand some things and Alex it might be worth checking out the top ranked flask from his video!
Yes the PF tests are always good. His was a vacuum-insulated bottle test, which subtly differs (despite the cross-over Yeti) from what I'd deem a flask.

All things Yeti are a ripoff. Much better products out there for much less.
Woot! Can't wait to hear more about Allen!
Nice review. I was on the fence but this helped me finalizing my decision and going with Thermos. Your research was convincing.

The Thermos in particular is a bargain. I've had problems with their cheap classic range though (the £10-15 ones).

I love your authoritative voice. You're a great narrator.

Me and a coworker are coming up with an lightweight thermos for mountaineering right now it’s just an idea but working out the concept
How’s that klean kanteen holding up?
i would like a test where you drop / toss the flasks off the top of alan into cold or freezing harbour water (obviusly attach a string to recover them) to see how they would fair in such a scenario and how much they would loose if submerged for a few hours, its something that can happen on an expedition, and even tho i dont explore much outside of some hiking trails, i like to keep a lanyard on my thermos for that (admittedly its more at risk of flying down a mountain than taking a swim in an ocean) very reason

Ask a rock or gem collector to use their tumbler (used for polishing stones). It should not damage the tumbler and you could always add rocks.

Happy to see some good testing.

You need to get the Stanley master series 1.3l flask
Stanley is the best overall imo
there's no surprise if the flask, with the best performance overall, has a double sealed top, with the classic plastic top screw + mug. the design is unbeatable and wins in both thermos flask and thermos mug comparisons. And almost too often, the victory goes to Stanley or Thermos. or those who has a too good of a copy product ;)
I think you're right. Trying to make 'easy drink' tops is always going to compromise raw performance.
What do you mean with your last comment, "that's the only place I'm allowed to put it?"
im down for some washing machine destruction, or maybe just drag them with a string from a bicycle or something like that XD
Why did you tape wood round the lid?
So you can unscrew the lid when it's frozen on.

Hire a cement mixer for a day and test them in there.
A more sensible idea.
I wish you had put a fake label on one of the cycles that said "flasks" or similar 🤣

I think once the vacuum fails fully, there's not much left to meaningfully test.
