THERMOS Stainless King Vacuum-Insulated Beverage Bottle, 40 Ounce, Matte Stainless Steel

Is simply outstanding. Its vacuum insulation truly delivers: it keeps drinks cold for hours and coffee hot almost the entire day. I’ve used it for travel, at the office, and even outdoors, and it always maintains the perfect temperature. The stainless steel design is sturdy, durable, and also looks elegant. The size is great—large enough to hold plenty of liquid without being too bulky. I also love that the lid doubles as a cup, which makes it even more practical. This is a reliable, high-quality bottle that is absolutely worth the investment. Highly recommended for anyone who wants to keep their drinks at the perfect temperature for hours!

Thermos is great. It kept our beverage hot for many hours. We will try a cold beverage next! It’s a good size to hold your liquid. The cap is tight, no leaks.

I absolutely love this thermos. Super durable yet dishwasher safe. Keeps my hot drinks steaming hot all day long, plus it holds significantly more liquid than most competing products. Pour spout is super easy to use and mess free. Truly the perfect thermos!

This is a high-quality, nicely sized thermos. Holds the temperature well and is easy to carry around due to its convenient handle. The stainless steel design is also cute, and the dual cap/cup is a nice traditional feature. You cannot go wrong with Thermos brand. The seller also shipped the product out fast, packaged well, and the price was irresistible!

This seems to keep my ice cold for 24 hours. I like the cup better than other thermos with drinking spouts. Silva seems to cause bacteria grout on spouts that smells. A cup is so much better.

THIS THERMOS IS AWESOME!!! I CAN PUT HOT COFFEE IN IT AND LEAVE IT IN THE CAR OVERNIGHT IN FREEZING TEMPS AND THE COFFEE IS STILL A LITTLE WARM THE NEXT DAY. KEEPS MY COFFEE VERY HOT ALL SHIFT AND THEN SOME. HAVEN'T TRIED ICE IN IT YET.

I bought this to keep water hot enough to brew tea a few hours after boiling, and boy howdy did it deliver. My husband wanted to hold afternoon tea for his mom for mother's day, with takeout from a local tea house, which includes loose leaf tea to brew at home. We wanted to bring everything to a park, so we packed up cute tea cups, and filled this thermos with boiling water to brew fresh tea when we arrived. I tested it's ability to retain heat before we used it for real, so I filled it halfway (one electric kettle full) with boiling water, closed it all the way, and forgot about it. Almost 2 days later, it's still hot enough to be uncomfy to leave your finger in, and certainly hot enough to brew tea. I found it easy to open and close, and I like the pour spouts on either side of the stopper that you can use when you unscrew it a bit, but really love that when it's fully tightened (with just normal grip strength, nothing crazy), it doesn't leak at all. That being said, this is definitely not a commuter drink it in the car travel mug, it's more of a campfire-side stationary use thermos, but it's still decently portable. Since it doesn't leak, you could easily use a carabiner to clip it to a backpack, or put it inside a larger backpack. I don't love the handle for constant holding, though- it's like those strange flat-collapsing handles you'd find on an old school metal lunchbox- so I wouldn't carry it around that way. As another reviewer mentioned, the care guide is inside the bottle, so make sure you remove that before you wash or use it. In these instructions, it does say it's top rack dishwasher safe (I'd love to know how on earth they think we're fitting a 40oz tumbler in the top rack of a dishwasher though), but recommends hand washing because dishwasher detergent is harsher and could hurt the finish. I'm a death-before-hand-wash girlie tho, so here's hoping it holds up in the bottom row of the dishwasher. It looks quite nice right now, but I'm not super pressed about it if that goes to crap from dishwasher use. I'm hopeful this will last us a very long time, but I'll update if/when it becomes unable to properly do it's job.

This thermos has made my life easier, it keeps my water hot for 24 hours it is great to take it to work, on a long trip or even to keep the water warm for a baby's milk

The best flask i ever used,it really keeps water hot upto 22 hrs!only one thing is missing,the carry strap.truly worth the money!

Best of best vale a pena

Excelente producto, el agua fría aguanta más de 12hrs y bien fría como recién sacada del refri y en cuanto a caliente, la llene de café caliente a las 6 am y la dejé olvidada, a las 8pm la abrí y el recipiente aún caliente y con vapor Excelente calidad en materiales y bastante práctica, ya sea para regalo de terceros o propio, es una delicia tenerlo a mano

Thermos is a brand that has always come to delivery excellent quality and durability and this product will be no exception. It's built extremely well and keeps things very hot / cold for the time claimed. I'm a bus driver and spend hours on the road with no time to pull over to grab a hot coffee so now I can take 40 ounces with me and it's hot when I want it. The things I don't like about this product that I wanted to mention here to help others is this: 1) The narrow spout makes it really difficult to clean the inside with a bristle brush. All you can do is fill it with warm soapy water and shake it. This makes getting the coffee/cream staining out of the steel impossible. It's not unsafe but it bothers me it's not 100% clean. 2) the care/use booklet is so tiny and was shoved inside the Thermos, I had a really hard time trying to get it out of there. Meanwhile the product tag is elastic banded to the top. Why couldn't the care/use booklet be the same sort of attachment instead of spending an hour trying to get the stupid thing out of the inside? Then once I got it out it was impossible to read without a magnifying glass because the text on the booklet is so tiny. 3) I would love if Thermos would get rid of the handle on the side and opt for a hookable loop on the top instead. This would keep it upright and be easy to hang off a napsack / drivers hook in my bus instead of hanging sideways. Who really uses the handle to carry it to work anymore? Hanging off a Carabiner would be much better. 4) It would be really nice if this came in some sort of packaging other than a clear bag thrown in the Amazon box for it to shake all around arrive slightly dented / scraped up. Not a big deal because it's going to encounter this sort of wear/tear with daily use but if it was a gift or something it would be nice to have it arrive in mint condition.
