The bottle is a great size, keeps my drinks nice and cold and the carrying handle is solid. I love the tab for holding the cap too!

Good bottle - poor design for transporting

The bottle is great for holding liquids cold and with the handle is easy to carry around. I also like the two screw tops for getting ice or liquids into the bottle. Though it is no good to transport - it does not fit in any car cup holders, which is why I barely use it. Basically useless unless you just want to carry it on a walk.

Broken after 1 year

I bought this one year ago and it’s already falling apart. I liked it while it was working but the design seems pretty shoddy for something so expensive.
No, I would not recommend this to a friend.

Still pretty good.

It wasn't as robust as the Classic bottle (see other review), but it does a pretty good. The ice definately didn't have the lifespan as the classic, but this is not designed to be as robust. This road trip was a westcoast 4300 miler and the temps were mostly cooler through British Columbia/ Glacier, Mt Rainier areas (40s-70s)(with small stint at 99 through Nevada and Yosemite).
It did the job, but needed daily ice refills even with just sitting in the center console area.
I don't want to seem like it's a bad bottle, it's just not a long lasting thermal insulator, but there are better choices, especially if you are going to carry it with you on hikes and want something cold down the path.

It is easy to carry and it keeps everything cold. My protien shake is still thick and yummy after a whole morning in my bottle.

Good overall

This bottle has good water capacity, 36 0z, After it is filled it is heavy. I like the handle and it is well constructed It some how bulky. I can not attest the efficiency to keep the water cool because I don’t drink cold water. What I think needs to be improved is the thread to close de large cap. It is not easy to close it but the top cap it is a good size and easy to close. At home we have the smaller version and it is much easier to handle it.
I would recommend this to a friend!

Great bottle.

Ibought the bottle in August 2025, and honestly, I’ve had a really good experience with it overall. The materials, the feel, and the overall quality have all been great. The only thing that disappointed me a bit was the lid design.
The lid comes in two separate pieces, and after about two weeks of use, I heard a small cracking sound when I closed the bottle. When I opened it again, one part of the lid had separated from the closing piece. I tried gluing it back together several times, but it kept coming apart. Eventually, I found a much stronger adhesive at a hardware store, and after fixing it with that, I haven’t had any issues since.
Other than that, I absolutely love the bottle, and I’m even considering buying another one just like it.
I would recommend this to a friend!

Perfect size for putting in a hiking pack. Keeps water cool and doesn’t leak.
