Obsessed with the glimmer pink!!!

I don’t usually drink out of a tumbler but I’ve been using my new Hydro Flask everywhere. I love that it’s leakproof and the color could not be more perfect - seriously glittery pink?! Say no more. It’s the perfect companion for while I’m working at home or heading to yoga. Thank you Hydro Flask!

[This review was collected as part of a promotion.] Perfect for my car's small cupholder but holds a lot of water. The bendable straw is the best also as I'm always on the go. I love it!

Great for gifting

[This review was collected as part of a promotion.] A 40 oz travel tumbler is a super practical everyday essential if you love staying hydrated without constant refills, want great temp control, and like having a reliable, reusable drink companion with you. It’s basically a larger water bottle, upgraded for real life.

[This review was collected as part of a promotion.] I already have 6 hydra flasks and my daughter has 4 so I feel that these tumblers and bottles we have are the best only thing we would like is an option to boot some of them.

straw leaks constantly
on December 27, 2025
Posted by: Anjana K.
[This review was collected as part of a promotion.] Extremely disappointed. The straw leaks constantly, creating a mess and making this 40 oz travel tumbler impractical for daily use. For a brand like Hydro Flask and at this price point, this is unacceptable.
I bought this with high expectations, assuming premium quality and thoughtful design—but a leaking straw is a basic failure. A travel tumbler should not require constant caution just to avoid spills.
This product does not meet Hydro Flask’s reputation, and I regret the purchase. I would not recommend it unless the straw design is fixed.

Needed a new water bottle and this delivered!

[This review was collected as part of a promotion.] I’m so happy I purchased this. I got a really good deal on it and engraving was also an option to customize it to my liking. I wanted to purchase a certain competitor cup because it was trendy but I have owned multiple Hydroflasks over the years and they were all great quality so I am quite the fan of Hydroflask. I would recommend this product to others.
