Kept my water hot for 24 hours
The best thermos for the mountains, keeps hot and cold for several hours, it is easy to use because you do not have to unscrew the cap. You can safely buy spare parts, I recommend it because it is very convenient
I use it on my bike because the cover can be opened and used with one hand. It is very good and the heat insulation is not bad.
The thermos keeps the heat for a long time, it's good to drink from and easy to clean. I recommend it :)
Practical for everyday life, it keeps both hot and cold well.
Very practical
I used one month only this bottle not even hot for two hours they told fourteen hours
The product is very nice.. it keeps cool.. the lid is useful.
I have several of these types of thermoses of different capacities. They keep things warm for a long time.
Great and practical for the car
I enjoy using it because it provides heat insulation for about 5 hours and is easy to use.
One of the best my son has used so far.
look, size and use super practical to take in a small backpack when hiking
It is of sufficient quality and its ability to keep warm is legendary. I had previously bought the 700 Luk thermos. The issue of accessing the spare lid was also very well thought out. How many thermoses have I had to throw away just because of the seal? I would say Decadlon quality and keep quiet.
Horrible
Additional Product Information
Composition
Bottle/Body: 100.0% Stainless Steel ; Lid: 81.0% Polypropylene, 8.0% Silicone, 10.0% Polyamide, 1.0% Stainless Steel
How is thermal insulation tested?
Lab-tested to EN 12546-1 standard at an ambient temperature of 68°F (20°C). When filled to capacity, it takes 14 hours for contents to drop from 203°F (95°C) to 122°F (50°C)—the point where drinks are still considered warm enough to enjoy.
The secret of the insulated flask?
This flask’s double-wall stainless steel with vacuum blocks heat transfer by conduction and convection. A copper layer reduces heat loss through radiation. For best performance, preheat the flask with hot water for 5 minutes, then replace with your drink and close tightly. The fuller the flask, the better the heat retention. Caution: liquids stay hot for many hours—use care when drinking.
Functions
Easily open the top with one hand by pressing the white “PRESS” button. To lock, slide the button down—when the red area appears, the lid is secure and won’t open. The top also includes a built-in filter to block large tea leaves or fruit pieces, though it’s not suitable for finely cut teas.
Care tips
Dishwasher safe (lid and body). Remove and dry with the lid off. The lid’s seal can be taken out for thorough cleaning—just be sure not to lose it/
First use
Rinse the entire bottle three times with clean water before first use

All materials used meet current food contact standards and are BPA-free, in line with French regulations. The bottle body is made from 18/8 (304) stainless steel, known for its food safety, while the lid is crafted from heat- and impact-resistant polypropylene.
