It’s good for long trips

Straw problems
[This review was collected as part of a promotion.] On the 64oz bottle, the straw doesn’t work unless it’s in the EXACT RIGHT position. And it doesn’t really stay there, so you have to hold it in place if you want to drink. Had I know, I never would have bought this model. I’m a big hydroflask fan and have owned and own many other bottles. But this 64oz has a major flaw.

LOVE IT!
[This review was collected as part of a promotion.] Buying this larger bottle worked perfectly, it is forcing me to drink far more water than before due to its larger size. Nice handle on it for easy carry and the cap is a breeze to use and clean.

I miss the original style. . .
[This review was collected as part of a promotion.] Any Hydroflask you choose will be excellent and I recommend them, however, I miss the old style that allows you to use the seam around the neck to attach an additional handle (mine is paracord). Admittedly the new style is sleek. The other thing I wish Hydroflask offered is a boot for the larger and smaller bottles then the ones they already have as I have been unable to find an aftermarket one as good as the factory ones. I also prefer the loop on the back of the straw top more than the handle now on the new style straw tops. Those couple of "issues" are minor and I still recommend Hydroflask to everyone!

Received as a Replacement
[This review was collected as part of a promotion.] Absolutely love my replacement, I had the original 64 oz wide mouth and the new one has such a great sleek design. Glad to be a happy and loyal customer of the hydro flask products.

not the same
[This review was collected as part of a promotion.] thank you for my replacement flask. I feel like the quality of these flasks are not the same as when this product first came out years ago. My ice would stay pretty much in tact all day in the original flasks. The last two flasks i've had just doesn't seem to keep my drink as cold. I fill my flask with ice in the morning and by dinner time, the ice have pretty much melted away. I still like my flask. . . . I just don't think it's as great a product as it used to be.

[This review was collected as part of a promotion.] I bought this for my son, and while he loves it, he says the ice melts too quickly.

When will you bring back customizable 64oz wide mouth bottles? I have to replace my current customized one (dropped too many times and so many dents and paint chips) but I need something that stands out! These colors are so muted :(
