Product Customer Reviews
So here we are on a product bordering on premium in relation to what we can find on the Market but at a Decathlon price! This bottle is a killer, I recommend it again and again!
really excellent water bottle, not very light but obviously to be thermal it cannot be otherwise, easy to open and close with one hand
Keeps water cool, durable, secure closure
Quality water bottle
The product preserves hot water for up to 8 hours. It is really very successful. I recommend it to everyone.
You can buy quality, solid products with confidence
I love it I use it every day
practical
This is my second bottle from Decathlon. The first one was identical in a different color version. Both were bought at promotional prices, about 30% cheaper than the initial price, which gives a really nice price option and a great price-quality ratio.
It worked in the mountains in February 2025, it had hot chocolate in it. It keeps warm for a long time.
Practical and keeps the water fresh until the next day
This is the second one I've changed despite the inconvenience. I use it for hot water and instant coffee, and the thermos doesn't last a year without the internal treatment deteriorating. We'll see if this one lasts longer.
I bought it to use at school, it is healthy, easy to clean, I feel comfortable, I am very pleased.
withstands hot and cold for a whole day. very good indeed. easy to use and transport
I used it mainly in the car during the summer months and it was sufficient for my daily water consumption.

How is heat insulation tested?
We’ve tested this flask in the lab according to Standard EN 12546-1, at an ambient temperature of 20°C while filled to capacity. The time it takes to drop from 95°C to 50°C (drinks temperature considered warm enough to drink) is 23 hours.
The secret of the insulated flask?
This insulated flask’s stainless steel double wall with vacuum blocks heat by conduction and convection. A thin layer of copper reduces thermal exchanges by radiation. A few tips to improve thermal insulation: fill your flask with warm water for 5 minutes, and then replace the water with your hot liquids, then close. The fuller the bottle, the better the heat retention.Warning: the flask is very insulating, the liquids will remain hot for a long time.
Functions
The top is easy to open with one hand by pressing on the white button marked InchPRESSInch. When carrying the flask, you can lock this button by sliding the white button down. A red area appears, indicating that the top is locked and it can no longer be pressed. The top has an integrated filter to keep large tea leaves or infused fruits out of your cup. Not suitable for very fine cut teas.
Care tips
Dishwasher safe (top + body) Be careful not to lose the top seals. Dry with the top off. The top's seal can be removed for a complete wash and dry.
First use
Rinse the entire product 3 times with clear water before using for the first time.
