I got a leaky one too.
on March 16, 2026
Posted by: Magen O.
[This review was collected as part of a promotion.] I'm disappointed because I usually really like HydroFlask products. So, even after reading the reviews saying that the lid of this model leaks, I figured that was a rare fluke and got one for myself. But lo and behold, mine leaks now too--to the point that I can't even use it anymore, but it is now too late to return it.

Cleaning
on March 12, 2026

[This review was collected as part of a promotion.] I find the lid slightly difficult to unscrew to clean, the cup size 20 oz is wonderful and my drink stays hot long enough for my need.

16oz and flex coffee lid!
on March 11, 2026

[This review was collected as part of a promotion.] I love my 20oz with chug lid but wanted something a bit different for my husband. His car’s chip holder is too small for most travel coffee cups, so I ordered the 16oz with coffee lid for him. He filled it with coffee and left for work, 6 hours later he was home and had me try his coffee. Still warm! He lives it. And the color odds perfect.

[This review was collected as part of a promotion.] I purchased the beachplum 20 oz coffee with flex sip lid. It isj just the right amount for my morning coffee and keeps the coffee hot. I'm using it all the time. Great purchase.

Same problem as last one immediately
on March 6, 2026
Posted by: Delia C.
[This review was collected as part of a promotion.] Hi! I sent in for the a warranty on my last one and literally the first day I had this one it fell off a table and got bent in the bottom at the corner of the bottle in the exact same weak point as my previous one and I feel certain it’s going to crack again overtime and start leaking! I’m so bummed! I really wanna be able to use this daily but it just isn’t remotely durable against even short drops which just doesn’t seem right given how the product is advertised and the price.

Coffee Tumbler 20oz
on February 25, 2026
Posted by: Vanessa P.
[This review was collected as part of a promotion.] Tumbler itself is great, but the lid is a hassle. It must come apart to clean, and it has several parts that are inefficient and not at all timesaving. I like that the tumbler is slim, travels well, and is easy to store.
