40 Ounce Mug
on July 28, 2026
Posted by: Bella S.
[This review was collected as part of a promotion.] This is my fifth purchase of this mug, one for me and four others as gifts. I LOVE this mug. The size is perfect, I drink much more water now because I always have my water with me. Very easily portable, fits in my car's cup holders, keeps my drink cold for a long time. I highly recommend this mug and many other Hydroflask products I own!

It's not what was expected

[This review was collected as part of a promotion.] The size of the cup and the design is great, but it does not keep your drink cold for 24hrs.

Favorite Work Tunbler
on July 19, 2026
Posted by: April R.
[This review was collected as part of a promotion.] This is my favorite tumbler to take to work. Perfect size, easy to carry, handles multiple drink types. My only improvement would be a screw lid so I could more easily shake to mix drink powders without any leak.

Color was different in person
on July 15, 2026
Posted by: Rebekah D.
[This review was collected as part of a promotion.] I love this bottle but the color was much more of a bubble gum pink. The pictures looked different than it did in person.

[This review was collected as part of a promotion.] Holds a lot of water, fits in our car drink holder, mostly doesn’t spill, stickers stick, and easy to hold
