Milton Vacuum Flask for Hot Drink 1 Litre (34 oz), Stainless Steel Double Walled Insulated Water Bottle for 24 Hour Hot and Cold Drinks with Cover, Leak Proof, BPA Free, Thermosteel Flip Lid 1000 ml

We’ve been using the Milton 1 Litre Vacuum Flask regularly for both hot drinks and cold drinks. We had a smaller size flask but had to upgrade it for our trip to Europe. We mainly used it for storing hot water and coffee, it performed consistently well during the trip. The build quality is solid—it feels sturdy in hand, it's not light, and has a practical design. I think the stainless steel body is resistant to dents and scratches, and the lid doubles as a cup, which is a convenient touch. The flask is easy to open and close, and the leak-proof seal has held up well over time. Also, the flask comes with a pouch so it's very easy to carry around. The colour is grey and looked like a standard flask. In terms of performance, it kept drinks hot for 12+ hours, which is ideal for day trips. We’ve tested it with boiling water in the morning, and it’s still hot by late afternoon. It also works well for keeping cold drinks chilled, making it versatile across seasons. Cleaning is straightforward—wide enough opening for a bottle brush, but because it's quite long and a little difficult to clean the bottom of the flask. The 1-litre capacity is generous without being bulky, striking a good balance between portability and volume.

​I bought this thermos to prepare my daughter's formula. ​I only used it for boiling water... I haven’t used it for any other drinks. ​It saved me from boiling water all night because it keeps the water hot, at least during the nighttime. ​I was hesitant because of the negative reviews, but after trying it, I will be honest: ​It keeps boiling water ((not hot water )) for only 11 hours. For the first 8 hours, the water is hot. After that, for about 4 hours, the water becomes warm, not very hot. ​Does it keep water hot for 24 hours? The answer is no. ​Does it leak? No. ​If you wash the lid thoroughly under running water and put it back, you might see a few drops when you flip the bottle—this is from washing the lid, not a leak from the inside. ​It’s possible that the reviews mentioning leaks were due to the product being dropped or damaged during shipping, and they have the right to return it. ​I noticed most people said the lid/cup fell apart. It seems they were using it for drinks. I never used it for anything but water. I believe the cup might not handle very hot liquids, which causes it to separate. If your goal is to use the cup for drinking, it’s not suitable. ​Regarding the included carrying bag, it feels cheaply made. Honestly, I haven’t used it.

Amazing was looking for the thermos that keep water warm for 12 hours and this thermos from Milton is amazing keep water warm more than 12 hours which is very convenient to make baby’s bottle when out and about . Great product definitely recommend this .

Shoulder strap could be longer to allow flask to be carried across the body as opposed to only hanging on one shoulder. Stays warm all day, good flask. I put my own strap on to the case.

I bought it as I am suggested to keep sipping on warm water in winters throughout the day. This thermos is 1litre with a cover that comes with it. Keeps the water warm all day. I am super pleased with this bottle and may buy another one for my son soon. Thankyou

Drinks stayed hot for more than 12 hours. Capacity good

Brilliant flask . Keeps drinks warm for over 24 hours .

I can’t express how much I love my Milton Vacuum Flask. As a busy parent, having a hot drink ready whenever I need it feels like a little luxury in the middle of chaos. This flask keeps my tea and coffee piping hot for hours—seriously, I’ve come back after a long outing and it’s still warm. It’s such a relief on those cold mornings or during late-night feeds when I just need that comforting sip. The size is perfect—500 ml is enough to keep me going without being bulky. It’s lightweight, easy to carry, and the design feels sturdy and reliable. Plus, no leaks! I can toss it in my bag without worrying about spills. Honestly, this flask has become my little lifesaver. If you’re always on the go and crave that hot drink to keep you sane, this is a must-have. It’s simple, practical, and makes life just a bit easier—and that means everything.

The bottle has stopped keeping warm after using for 10 days. Very poor quality.
