[This review was collected as part of a promotion.] The engraving is super cute and I LOVE the color, however I wish the silicone straw didn't collect dust as easily.

[This review was collected as part of a promotion.] I’ve been buying hydroflask for over 10 years and this is probably the coolest color they have came out with! Love it.

[This review was collected as part of a promotion.] I got the new hydro that just came out, the one that glitters and it’s not at all like the photo. I was a little disappointed

LOVE LOVE LOVE!!!!

[This review was collected as part of a promotion.] I brought the 40oz travel tumbler! I love the design of it! How the lid easy pop off instead of twisting the lid off, it is soooo easy to clean! I love the flexible bendy straw it made it enjoyable to drink more water. I can you not I would drink 3 40oz a day and that’s more then I usually drink. I highly recommend!!!

Scuffed a bit
on November 15, 2025
Posted by: Karlie J.
[This review was collected as part of a promotion.] I bought two of these cups, one for my mom and one for my dad. I got them engraved with mom and dad and some of the offered designs. I am a loyal hydro customer although I’ve never bought from the site or had things engraved before. I love the cups and they came out beautiful but came with a few blacks scuffs. Most of the scuffs rubbed off but one stayed. This has not really changed my opinion on hydro I still love the cups just be prepared if you get them engraved to have a couple marks.

My first tumbler
on November 12, 2025
Posted by: Kulthum
This tumbler has more than met my expectations. I’ve had it for over a year, taken it everywhere with me, and it has held up very well with no scratching of the coating.
