Hydro Flask
12 Oz Insulated Mug

It features a BPA-free construction, a handle, and a lid, and measures 3.25 by 4.5 inches; however, it must be hand-washed and is not suitable for microwave or freezer use.

Product Insights
The Hydro Flask 12 Oz Insulated Mug is a lightweight (227 g, 100 g lighter than Yeti, feels like ceramic) mug with TempShield insulation that keeps drinks steaming hot for 1–2 hours, warm for 3.5 hours, and cold below 50°F for 6+ hours. The handle stays cool even with boiling liquid inside. The press-in lid offers high spill resistance (9/10) and multi-vessel compatibility, and the slider opens wide for straws and chugging. However, buyers report the lid can leak when knocked over despite being labeled watertight, the 3.25-inch base does not fit most car cup holders, the rubbery soft-touch coating wears faster than Hydro Flask's powder coat and degrades with dishwasher heat, and the lid has hard-to-clean crevices and requires hand-washing. It is best for stationary sipping at desks, tables, or campsites. GQ named it Best Travel Mug with a Handle in 2024.

Tasse à café
Idéal pour mon travail, grosseur idéal et fini les cafés froids!
Excellent Purchase
This cup keeps your coffee HOT! I use it everyday and it keeps my coffee HOT for over an hour. Even after 2 hours, my coffee is still warm enough to enjoy. I like the style of a cup with a handle and the lip isn't overly thick like some insulated mugs. No regrets on this purchase.

Love this mug

Reddit Insights
4 threads · r/BuyItForLife, r/Hydroflask, r/CoffeeReddit users have mixed feelings about the Hydro Flask 12 oz insulated mug: many praise its excellent heat retention and sturdy build, but common complaints include a non-leakproof lid, rubber coating wear, and occasional defective units.
Positive aspects like heat retention and build quality are frequently mentioned, but issues with lid seal, coating durability, and some units failing to keep hot lead to an overall mixed but leaning positive sentiment.

- Commuting and travel, mug fits some cup holders and is secure in bag
Watch Out For
Compared To
vs Yeti
Yeti is often preferred for its dishwasher-safe, leakproof mag slide lid and better lid durability, though Hydro Flask wins on aesthetics and lighter weight for some.
vs Klean Kanteen
Klean Kanteen is praised for longevity and easy cleaning, but Hydro Flask's rubber grip and design appeal to some users.
vs Zojirushi
Zojirushi offers extreme insulation that some find overkill; Hydro Flask is more balanced for coffee drinking.

Hydro Flask coffee mug secure but lid annoying
I like my hydroflask coffee mug, but the lid is kind of a pain to take off and wash. It definitely feels secure in a bag though! It’s only ever lost the lid when dropped on concrete while running for a bus, and only has a small nick.

Hydro Flask coffee mug not dishwasher safe and coating wears
I like it, but I feel like there’s better cups out there. It’s not dishwasher safe or spill proof. The rubbery stuff on the outside doesn’t seem to be lasting that well on mine, when compared to the powder coat of my water bottle.

12oz mug keeps coffee hot, lid off to cool
I love mine. Lets you take your time drinking the coffee, or you can take the lid off if you want it to cool off.

Mug should keep coffee hot; counterfeit/faulty units exist
Between my wife and myself, we have 3 coffee cups by Hydro Flask, and I’ve bought a counterfeit bottle in the past. What you’re experiencing is not normal.
