Great, but a little upset

[This review was collected as part of a promotion.] Right after we bought this, they released a Hydroflask promotion for free engraving… would’ve appreciated that with our hydros as well. But great product.

Goes everywhere with me

[This review was collected as part of a promotion.] Thank you for the sale. I have always been advised to hydrate more. Costs of these products have been prohibitive for me until now. This Tumbler's construction is excellent and the quality shows. It functions as promised and is highly valued. Thank you again.

[This review was collected as part of a promotion.] I was not sure about the design with the handle at first. I am very pleased with it. It is easier to lift than the 32oz bottle for my aching hands even when full. Love the color which I coordinated with a pink boot. I ham having fun buying accessories for the tumbler. So far no problems with leaking. Very well made.

Coldness?
on July 5, 2026
Posted by: Theresa D.
[This review was collected as part of a promotion.] It doesn't seem to keep drinks as cold as my other "sealed" Hydroflasks. I do like the ability to take the lid apart to wash it completely. The newer lids with the movable drink spout can't be broken down the way the older ones can. It collects a lot of gunk around the hinge area.

You need this tumbler!!
on July 3, 2026

I filled this tumbler up with ice water and left it outside in direct sunlight on a metal grill in 103 ⁰ f weather for almost 9 hours and there was still ice in it. . I have also left it in a black interior car on a 90⁰ f day for 7 hours and there was still ice in it as well. I highly recommend it for this summer. .
