Great except one thing

[This review was collected as part of a promotion.] I love all things HydroFlask but have t bought anything in a while. I’m replacing a few of my older bottles and was surprised to find that there aren’t rubber pieces on the bottom. These helped with keeping the sound quiet when placing the bottles down, as well keeping my tables from being marred. Why are these not in there anymore?

Encourages me to drink water
on December 14, 2025

[This review was collected as part of a promotion.] I have another hydroflask product - 32oz wide mouth screw top. I didn't want to make this purchase because I felt I didn't "need" another water bottle. I wanted something that 1) held more water to minimize how often I was refilling it and 2) was faster to drink. I'm so glad I caved because this was exactly what I wanted. It's PERFECT for work or to drive around town ❤️ and it's not too heavy filled

The best tumbler
on December 7, 2025

I love these - I probably have about 10. The handle makes it really easy to pick up, and the large size definitely helps me to drink more water throughout the day. I love the orange color. So retro looking.

Everyday Tumbler!

[This review was collected as part of a promotion.] This goes everywhere with me. Love all my tumblers. The only thing I would change is that it does leak when slightly tipped, otherwise, this is a definite win!

Fits the cup holder!

I have one of these in the 32 ounce size and liked it so well that I wanted the 40 ounce size. Fits great in my cup holder and keeps my beverage cold all day.

Functional, cute, and doesn't leak
on December 5, 2025

I've been borrowing my mom's tumbler since I left my regular Hydro Flask water bottle with my friend. I love it so much that I had to buy one for myself. The color choices are so cool and I ended up getting moonshadow which is such a pretty shade of purple. I've been loyal to Hydro Flask since I was in high school in 2015 and have not cheated on her since.

I do not like that
on December 4, 2025
Posted by: Alexandra L.
[This review was collected as part of a promotion.] I do not like that if the cup accidentally tips over, it leaks. Also, does not keep ice for very long at all. I love hydroflask typically, but this tumbler is just not for me. Going back to brumate, sorry
