Hydraflow Hybrid - Triple Wall Vacuum Insulated Water Bottle with Flip Straw (25oz, Powder Graphite) Stainless Steel Metal Thermos, Reusable Leak Proof BPA-FREE for Sports and Travel

Perfect size to fit in most vehicle drink holders. Nice quality, keeps my drink cold. Haven't used it for hot beverages but pretty sure it would hold the heat too. I have two and use them daily to reduce plastic waste.

Dearest Readers,I have been informed of a most exceptional water bottle that has captured the attention of the ton. The Hydraflow Hybrid is said to be a paragon of hydration, offering both style and functionality.Its sleek design is both pleasing to the eye and practical, as it fits effortlessly into even the most diminutive of cup holders. The temperature-regulating properties are said to be unparalleled, ensuring one's beverage remains at the desired temperature for extended periods.While this vessel is undoubtedly a triumph of modern engineering, a minor flaw has been noted. The metal exterior is susceptible to dents, a circumstance that could mar its appearance over time. A protective covering of some sort would be a welcome addition.Nevertheless, this water bottle is a must-have for those who value both form and function.Yours truly,Lady Whistledown

I am very pleased with this purchase. The bottle is slim and a lovely color; the cap and seal fits tightly so there are no leaks even if upside down in my totebag, and cold water stays cold for the day, even when out in the sun. The water tastes fresh all day, no plastic to impart that chemical taste. I find the flip-top of the straw convenient, although others have told me they find it uncomfortable. I like it because I can drink from this bottle even when lying down in bed. And, the price is half what I found with other recommended brands. This one's a winner!

I brought this water bottle with me on my last Disney trip. It was the perfect size for my small backpack. I liked that there was a comfortable strap on top so I could carry it around with me for a bit while I was drinking out of it. It kept my water cold throughout the day. I put ice in it around 4pm and there was still some ice in the bottle the following morning. It was tipped on its side for a bit at one point and leaked out a little, but the lid needs to be tightened just right or it's not on correctly.

I’ve tried multiple water bottles, but this one is my favorite. I can confirm that ice has lasted in my water bottle for over 24 hours. Not sure about heated stuff I’ve never had to use it for that. The handle makes it very easy to carry. With the press and drink from the tip and straw, I like that I don’t have to turn my bottle upside down to drink it. The only flaw(That’s kind of unavoidable for clumsy me) is that the bottle can dent if you drop it on a hard surface. So I do recommend a silicone boot cover for the bottle. They sell them separate on Amazon as well! Just make sure you get the right size for your bottle.

So let me be upfront. Don't buy this! It doesn't hold temperature and my best guess is it doesn't actually have a vacuum between the walls. That leads me to my next issue with the company's lack of honesty. They claim "triple wall" which doesn't exist. The only accepted moniker in this industry is "triple layer" which refers to the standard two wall construction with the addition of a layer of copper which helps prevent "radiation" type heat transfer. (For the uninspired there are 3 methods of heat transfer which is convection, conduction, and radiation. The vacuum chamber only stops convection & conduction but not radiation. The copper layer supposed to help with the radiation component.) There lies the problem...If you see in the pictures, the outside temperature of the flask jumps 15°F in six minutes for a mild hot internal temp of 112°F. So like I said there must not be a proper vacuum between the walls. Particularly since the copper layer supposed to add efficiency by limiting radiation heat transfer. But nope, it's a big failure.Problems other than the whole not insulated thing: the silicone valve which allows air into the bottle as you suck on what feels like a flat pen*s. The valve sticks most of the time even after trying to work it loose and is quite annoying. I lost $15 on this and the sad part is the Ozark Trail open mouth version I bought at Walmart for $9 actually works very very well. Now it's just more waste when I'm trying to do better. Well you can do better now I have given you honest and important information.

Keeps drinks very cool and great size

I was very excited about this bottle — all the features I wanted in a perfect size. I was trying it and another bottle out ahead of a long trip. Only a few days in, I realized it was leaking around the seal of the mouthpiece, and there was no good way to make it stop. I hope that this was just a one off thing, but I wouldn’t order again.
