Mug - Stainless Steel Reusable Tea Coffee Travel Mug - Vacuum Insulated, BPA-Free, Non-Toxic Black 6 oz

I’ve been really enjoying this 12 oz Hydro Flask mug as part of my daily routine. It does a great job keeping coffee and tea warm while I’m working. I haven’t specifically tested the advertised 5–6 hours of heat retention, but for my typical use—drinking within 1–2 hours—it performs perfectly. The size is ideal, feels solid, and it’s easy to use at my desk without worrying about my drink cooling off too quickly. Overall, it’s a reliable, well-made mug that fits nicely into a workday workflow.

I recently put the Hydro Flask coffee mug 6 Oz to the test to see how well it keeps beverages hot. Starting with a cold mug, I poured in 6 oz of hot water and used a digital thermometer to take readings every 15 minutes. Right off the bat, I was impressed by the sleek design and comfortable grip. The lid seals well, preventing any spills, which is a big plus. Testing Results: At the start, the temperature was a solid **182°F**. Here’s how it measured over time: - 0 minutes: 182°F - 15 minutes: 169°F (drop of 13°F) - 30 minutes: 162°F (drop of 7°F) - 45 minutes: 155°F (drop of 7°F) - 60 minutes: 148°F (drop of 7°F) - 75 minutes: 142°F (drop of 6°F) - 90 minutes: 138°F (drop of 4°F) - 105 minutes: 133°F (drop of 5°F) - 120 minutes: 129°F (drop of 4°F) Performance Analysis: The mug did a fantastic job of keeping the coffee warm. After an hour, it was still at 148°F, which is above the typical industry standard of 140°F. Even after 120 minutes, it held steady at 129°F, making for a pleasant drinking experience. Overall, I think the Hydro Flask coffee mug is a great choice for anyone who likes their drinks hot for a couple of hours. However, if you're looking for something that will keep your coffee piping hot for several hours, this might not be the best option. Personally, I enjoy sipping my coffee while it’s still warm, and for that, this mug hits the mark perfectly. If you want a reliable and stylish insulated mug, the Hydro Flask is definitely worth considering

This Hydro Flask insulated stainless steel coffee mug performs exactly as expected. It keeps beverages hot for significantly longer than a normal ceramic mug, which makes a noticeable difference if you tend to sip your coffee over time rather than finishing it quickly. The build quality feels solid and durable, and the insulation works well without making the exterior hot to the touch. It’s comfortable to hold, and the lid fits securely, helping retain heat while reducing spills. Cleaning has been easy so far, and it doesn’t retain odors or flavors. One thing to note is that, like most insulated mugs, it’s slightly heavier than a standard mug, but that’s expected given the construction and insulation. Overall, this is a well-made, reliable coffee mug for home or office use if you want your drinks to stay hot longer without needing a warmer or microwave.

The Hydro Flask Coffee Mug – Insulated Stainless is excellent for keeping drinks hot for a long time! It has great insulation, a sturdy feel, and a comfortable handle. The lid helps prevent spills, and it’s perfect for coffee at home, work, or on the go. High-quality and very reliable for daily use.

My New Year’s resolution (which I started halfway through December) was to cut out energy drinks, and I needed a mug that I could bring to work that would keep my tea warm, even when I stepped away from it for too long. I have a 32oz Hydroflask from college I still use, but don’t want to put anything other than water in that one. The 12oz is the perfect size for my batches of hot tea, and it fits in my cup holder for my car (which has a gap for the handle to fit in). While it still keeps my tea hot a lot longer than just a regular mug, it doesn’t keep it comfortably hot for longer than an hour or so if left unattended with the lid fully on, which I think is a fault of the thinner, less insulated lid, as well as probably the size being so small. If the lid was a bit more insulated, it could probably stay hot for longer, even at this small size. I usually drink my tea within the hour, but there are times my ADHD takes over and I forget about it, and come back to a warm-to-tepid cup of tea after a couple hours. Great mug if you’re relatively quick about drinking your tea, though (within an hour or so of brewing). The lid isn’t spillproof, but I haven’t really knocked this over. The bottom of the mug is the same matte, almost silicone-feeling texture as the rest of the mug, so it’s not prone to sliding around on a desk easily. Haven’t tested it in a dishwasher, as I prefer handwashing, but I’m sure it’ll hold up just fine.

I am absolutely thrilled with my new 12 oz Hydro Flask Coffee Mug in Trillium Pink. This mug is the perfect size for my morning routine, fitting neatly under my home brewer and feeling comfortable to hold. The insulation is fantastic; it keeps my coffee steaming hot for hours, which means I can actually enjoy it hot even when I get distracted. The lid is what sets it apart, though—it is truly leak resistant, and while I wouldn't throw it upside down in a backpack, it handles jostling in the car perfectly without any accidental spills. The Trillium Pink color is vibrant and cheerful, and the stainless steel is easy to clean and doesn't hold onto old coffee smells. It is durable, stylish, and exactly what I needed for a reliable daily travel mug.

Perfect mug for bringing on a mountain hike. Nice and small and easy to pack away. It cleans up very well and is extremely durable. The lid fits nice and tight yo prevent spilling. It keeps you drink or soup nice and warm. Definitely worth the money and a mug that will go on several more hiking trips for sure!

This is a review of Hydro Flask Stainless Steel Reusable Mug - Vacuum Insulated, BPA-Free, Non-Toxic I really love this 12 ounce Hydro flask insulated mug. The coating of the outside of the mug is kind of soft feeling and when you put it on a hard surface it doesn't clink like something that would just be plain metal. I also like the way that the spout opens and closes on the top. Although the spout cover is not leak proof, that doesn't bother me because this is a coffee mug, and I don't normally place a coffee mug on its side. I also like the rounded handle which is very comfortable to put my fingers through and whether you put two or three fingers through it then you can use your little finger or second finger to sort of go underneath it and support the mug. My only minor issue is that they recommend that you hand wash this and I think that's probably to protect the finish on the mug. I really like the look of the mug and I don't want to risk it so I will hand wash this, and that's not that big of a deal. My Ninja coffee make brews coffee at 177°. I've measured the temperature using a digital thermometer and an hour later the mug still keeps my coffee about 150 to 155°. An hour after that it's still warm enough to be comfortable drinking but not what I would call tepid. So this basically keeps my coffee hot for two hours which is awesome. I like the different colors that this is available in. I think it's a solid purchase.

Over priced and doesnt even keep my coffee warm for an hour. The lid is useless, I am not sure why there is a small tiny hole on the lid. Wrong information shared in the product description.

Amazing for insulation but it definitely leaks :(

very small

Super tasse garde au chaud et au froid

I Nice cup. Lightweight for a 750ml cup. The exterior of the cup remains cool even when filled with hot water.
