Best water bottle in the house
on September 14, 2026
Posted by: Kate D.
[This review was collected as part of a promotion.] This is the best water bottle I’ve ever had. It’s customized so I love the colors. It keeps my water cold and fresh, and everyone in the family likes drinking from it. I love knowing that it’s a safe cup. Going to purchase one for my kiddo too.

Glimmer Pink without the pink?
on September 14, 2026
Posted by: Laurie
I was surprised when I received this in the Glimmer Pink color. There's hardly any color to it at all. It's a grayish, pale white with maybe a whisper of pink - or maybe I'm just trying to imagine it into being. The color on the site is drastically different. The Hydroflask logo is also stainless steel - there's no gold like in the pictures.

I would change a couple of things
on September 1, 2026

[This review was collected as part of a promotion.] All in all, i am very satisfied with the hydro tumber 40oz in purple. I would change 2 things. Make a boot that fits the tumber better, offer fitted straw cover caps, and the straw mechanisms need rethinking. I love a silicone straw. I dislike the center part where the in cup straw attaches to the drinking straw. It isnt very secure.

[This review was collected as part of a promotion.] Fits perfect in my cars cup holder . The best thing is the straw… the straw has an angle tip so it is easy to find in my draw of straws. .

[This review was collected as part of a promotion.] I am surprised it doesn’t keep my beverages as cold for as long period of time as the my others do, which cost significantly less $.
