Hybrid - 25oz Triple Wall Vacuum Insulated Bottle - Powder Graphite

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 iced drinks cold overnight.Love the feel of the built in straw.Easy to clean and carry. Fits in car drink holder and my purse.I have three. Tempted to order another.

I have hurt hands from years of repetitive movements. This product is much easier to use/carry than my water glasses. The soft sip straw is easy on my mouth,teeth and lips. Keeps my beverages cold and keeps drink(a) relatively free from other people's germs (coughs/sneezes/etc...).

I am on the go a lot, so it is easy to carry, and it does stay cold for a long time.My friend showed me hers, and I liked it.

Bought this bottle for my daughter who is 10. First off, it was easy to clean, the water stayed cold for so long and the ice remained ice until way after she got home from school. It’ll keep the ice for 15hrs and water cold for more than 18hrs, if she doesn’t drink it out during the day. It’s lightweight and easy to use. Only issue was when the bottle fell, the lid broke. I tried looking for a replacement lid, but did not find anything. Other than that, we loved the bottle while we had it.
