It's really worth investing in a decent thermos. Warm coffee after 6 hours hits the spot much better than lukewarm. It keeps the heat well. It's great that there are two caps included and it's nice to have the option to pour into two cups. And the texture of the paint is very pleasant. It feels good to hold. The larger size is only a plus, as it doesn't take up much more space and you can share with someone.

It keeps the temperature perfectly during trips. I bought the green one, I have to admit it was on sale. The color doesn't matter, it does the job. I use it for everyday work because nobody wants to make coffee for workers anymore.

I highly recommend, very nice thermos! I was considering a larger capacity but 0.7 liters of coffee or tea is definitely enough for a few good hours. Nothing leaks, huge plus, and the build quality is great.

I chose this thermos for work and trips because the capacity of 0.75 l is ideal for me: it's not too small, and at the same time not as big as the one-litre model. It keeps the temperature at a good level – in the morning I pour in tea and after a few hours it's still very warm. The Olive Green colour is practical, the thermos looks good and small scratches are not visible on it. There is one detail: when filling with boiling water, the first sips may be too hot, so I usually let the drink cool down a bit. After sweet drinks, it's worth rinsing the thermos immediately to get rid of the smell. To sum up – a simple, solid thermos that is worth its price.

Great thermal bottle, perfectly fulfilling its main role, which is to keep beverages at the right temperature. The outer coating may feel a bit 'sticky', but it provides a solid grip in the hand. It is very functional thanks to the presence of two cups and a double locking system.

I considered a thermos from another company. I chose ESBIT because of other products from this company. As usual, I was not disappointed. I use the thermos every day in various field situations (forests, training grounds). It works great and keeps the heat very well! Hot coffee/tea/water is perfect.

Very good quality equipment for really little money. The thermos set includes two cups and two different stoppers. This is my next product from Esbit and definitely not the last one. Very good workmanship, works even better than you might expect and has never had any problems.

I wholeheartedly recommend this thermos. When it was -8 degrees outside, after 7 hours the tea was still hot, and even after 24 hours it was still warm. Additionally, the two cups are a big advantage.

Thermos tested in the field. With an outside temperature a few degrees above 0°C, the tea was still lukewarm after 24 hours. After 12 hours, it was very warm (the assessment of the temperature is quite subjective). At -7°C, after 5 hours in the field, the tea was hot. The best thermos I have owned so far. Extra point for the double cup.

We were looking for a new thermos because my previous one didn't keep heat long enough, which always irritated me. The most important thing for us was that the tea stayed hot as long as possible. Now the problem is solved, and additionally, the thermos in Olive Green looks excellent.

Very nice, solid, and spacious thermos. It has quite a large circumference, so you need to make room for it in your backpack, but it works perfectly. It keeps heat for a very long time.

Thermos purchased on October 17, 2025, 16:49; delivery October 18, 2025, 07:04. Shock! Respect. P.S The thermos keeps drinks hot for a very long time—after 23 hours, the drink was still hot. I RECOMMEND MILITARIA.PL as well as the ESBIT 1l thermos.

I chose Esbit because I’ve had one of their thermoses for almost 10 years. I knew it wouldn’t let me down. Now I can have both tea and coffee at hand at the same time. It’s nice that they’ve kept up the standard, still adding two cups and two types of caps.

It keeps the temperature very well. After 12 hours it's still hot, after 24 hours it's still warm enough to heat up. Tested in weather: heavy rain, strong wind, about 10 degrees Celsius. The only downside is the paint, which feels nice to the touch, but after one fishing trip, where the thermos was standing on the ground, tipped over a few times, and maybe rolled a bit, it got really scuffed, the paint came off, and you can already see the silver color (probably aluminum). I give 4 stars for heat retention, minus one star for that paint.

The best thermos I've had so far. It keeps the temperature the whole day even in really extreme conditions. It's also great in summer if you want to keep ice cubes inside, as they don't melt for many hours even in strong sunlight.
