Not as advertised
on April 7, 2026
Posted by: Damien R.
[This review was collected as part of a promotion.] I bought this item solely for how it’s advertised 24 hours cold 12 hours hot rating.
I preheat the cup both times I used it and barely got 5 hours hot

Great insulation - perfect size :)
on April 7, 2026
Posted by: Brandy L.
[This review was collected as part of a promotion.] I love this thing! It’s the perfect, easy-to-carry size; it’s 100% leak-free and keeps my hot beverages well insulated all day.
I also love the color (kind of a dusty blue). HydroFlask did not disappoint!

[This review was collected as part of a promotion.] Bought this cup for my little ones to put in their back packs while traveling. It keeps drinks hot or cold. Love it and kid approved!

New one to replace an old one
on March 30, 2026
Posted by: Anonymous
[This review was collected as part of a promotion.] I had a Hydro Flask for about 10 years, and some of the plastic in the lid was deteriorating, so it was time for a new one. They truly keep my coffee hot for hours, and the metal body lasts. I wish I could have gotten a replacement top for my old one, but that wasn't an option as the design had changed.

The Seal Falls Out!
on March 27, 2026
Posted by: Judith C.
[This review was collected as part of a promotion.] The second time I used this the seal fell out when I took the lid off to fill it with coffee. It falls out almost every time I use it. When I put it back, sometimes it still leaks. I have to be very careful with it. It does keep my coffee hot, but it is a pain.

The product failed. It did
on March 22, 2026
Posted by: Hope D.
[This review was collected as part of a promotion.] The product failed. It did not keep the liquid hot or cold. I was disappointed. In the past, I have found Hydro Flask to be a great product. This go-around, I ordered 2 different styles and both did not measure up.
