Makes my tea drinking better!

Large enough that it’s enough tea for my entire morning yet stays warm. Can switch lids to suit your preference. My only regret in buying this is that I didn’t get it engraved!

Specifications by Hydro Flask say

[This review was collected as part of a promotion.] Specifications by Hydro Flask say it keeps hot drinks hot for 12 hours. It does not even come close, more like 2-3 hours. Very disappointed with this flask. My old flask by another brand definitely kept hot drinks hot for up to 12 hours. Even more surprising is that this is a brand-new flask that I received from Hydro Flask to replace my old 20 oz Hydro Flask.

Second lid starting to leak

[This review was collected as part of a promotion.] I was so sad when I lost my 4 year old hydroflask this summer! It was the only travel mug I'd ever found that didn't leak coffee, so I used it every day, for years. I bought two new hydroflasks, even though they had this new lid design. One of the two lids was fine at first but started leaking after 3 weeks. I have now switched to using the second lid only, but this week i noticed a small amount of coffee along the seams when I tilted it for use. i am so disappointed! My previous experience had been nothing but spectacular. Now I have two new expensive travel mugs as leaky as all the others I paid a lot less for.

Good, but lid is impossible to clean

The bottle itself is good. easy to sip from it with one hand. Perfect for morning coffee while reading news. The only problem: it has a "flex sip" lid on it, and the lid is impossible to clean. I have the same problem as in another review by Angela: black gunk builds up in the layers of the lid and occasionally falls out into the drink or clogs the siping hole. (I put milk in my coffee, and I think that adds to the gunk also). This is not a manufacturing error -- this is a serious design FLAW!
