My 3rd one!
on April 30, 2026
Posted by: Shelley A.
[This review was collected as part of a promotion.] I love this so much because it's big enough to leave room for cream and it doesn't spill in my work bag like a lidded cup does.

Great purchase
on April 30, 2026
Posted by: Shawn S.
[This review was collected as part of a promotion.] I'm enjoying my purchase. I love how the top comes apart to clean thoroughly. It's coffee warm for a long time. Only issue I've experienced is that when you take a drink most times it will drip a drip or two when finishing. Would definitely buy again.

Cap isn't that easy operate compared to other
on April 17, 2026

[This review was collected as part of a promotion.] Cap isn't that easy to operate. When I try to close it and if I don't tight full it will leak and if I do extra tight, the cap opens as if I am ready to clean the top of the cap.

Love the size

[This review was collected as part of a promotion.] I got the dark red and I love this size but the color was a little too dark. I have it in other colors so decided to return this one.

Lids…
on April 12, 2026
Posted by: Anonymous
After using my Hydro Flask for many years, I’m finally giving up and I switched to a Zojirushi for my coffee. The flask itself is fine, but the lids are a terrible design. The flask originally came with the flip lid, which would give you a coffee nose ever time you sipped from it if you didn’t wipe the rubber stopper. The new twist and sip lids are just maddening. Coffee leaks and dribbles down the side and drips onto my clothes when I drink from it. I’ve ruined countless items in my backpack when transporting because I thought the lid was closed all the way and it wasn’t, and to clean the lid is just way more hassle than it should be to clean a lid. Hydro Flask, fix your lid engineering issue and might give you another chance.
