It is worth investing in a good thermos – after 6 hours, the coffee is still hot, not just warm. It keeps heat really well. I like that the set comes with two caps and you can pour the drink into two cups. The thermos coating feels pleasant to the touch and fits securely in the hand. Its size is an advantage – it does not take up much space, and you can share your drink with another person.

The thermos perfectly keeps the temperature during trips. I chose the green one because it was on sale – the color didn't matter to me. I use it every day at work, because nowadays no one wants to make coffee for contractors anymore.

I highly recommend this thermos, it's really great! I considered buying a bigger one, but 0.7 liters of coffee or tea is enough for several hours. Nothing leaks, which is a big advantage, and the quality is excellent.

I took this thermos to work and on trips because 0.75 liters is just the right volume for me: it's neither small nor a “brick” of a liter. It keeps heat well – I pour tea in the morning, and after several hours it’s still really hot. Olive Green is practical, looks good, and small scuffs aren’t as visible. A minor point: if you pour in boiling water, the first sips might burn, so I usually let it stand for a bit. Also, after sweet drinks, it’s best to wash it right away since it's harder to remove the smell later. Overall, the thermos is simple, reliable, and does its job for the money.

Very good insulated water bottle, effective at its main function of keeping drinks at temperature. The exterior coating may feel a bit 'sticky' but it provides a good grip for handling. Very practical with its two cups and two closing systems.

I was considering buying a thermos from another manufacturer. However, I chose ESBIT because I have had positive experiences with their other products. Once again, I was not disappointed. The thermos accompanies me every day in various outdoor conditions (forests, training grounds) and performs excellently—it keeps drinks hot for a long time. Coffee, tea, or water stay hot for many hours.

Equipment of great quality at a very affordable price. The set includes two cups and two different caps along with the thermos. This is another Esbit product I’ve bought, and definitely not the last. Very solidly made, works better than I expected, and has never caused any problems.

I can only recommend the thermos. At an outside temperature of -8 degrees, the tea was still hot after 7 hours. And after 24 hours it was still lukewarm. And the two cups are definitely an advantage.

The thermos was tested during outdoor use. When the ambient temperature was a few degrees above zero, after 24 hours the tea was still slightly warm. After 12 hours, it was still very hot (although that is a subjective assessment). At -7°C, after 5 hours, the drink remained hot. This is the best thermos I've had so far. An additional advantage is the two cups.

I was looking for a replacement for my old thermos that needed to be replaced, and the main criterion was to keep the tea hot for as long as possible, because I was always frustrated that the tea cooled too quickly in the old thermos. Now the problem is solved, and on top of that, it looks great in Olive Green.

Great, durable, and capacious thermos. It is a bit wide, so you need to make room for it in your backpack, but it works excellently and keeps the temperature for a very long time.

I bought the thermos on October 17, 2025 at 16:49, and the delivery arrived as early as October 18 at 7:04 – amazing, congratulations. The thermos itself keeps warm for a very long time – even after 23 hours the drink was hot. I recommend both MILITARIA.PL and the ESBIT 1l thermos.

I chose the Esbit brand because I have been using their thermos for almost a decade and I know it is reliable. Now I can have both tea and coffee on hand at the same time. I’m glad they still maintain high quality, offering two cups and two different caps.

The thermos keeps temperature perfectly – even after 12 hours the drink remains hot, and after 24 hours it is still warm and you can warm up with it. It was tested under harsh conditions, such as strong wind, heavy rain, and around 10°C. My only complaint is about the coating – although it is pleasant to the touch, the paint wears off very easily. After just one fishing trip, when the thermos fell over and rolled several times, it got scratched and silver marks appeared. For heat retention I give 4 stars, I deduct one for poor paint durability.

This is the best thermos I have had so far. It keeps the temperature for a whole day, even in very harsh conditions. It also works perfectly in the summer when I use it to store ice cubes – they don’t melt even after several hours in strong sun.
