You can open the quick-release lid with one hand by lifting the white latch. Close it by pressing the latch or by screwing the cup back on. A removable tea filter is attached to the lid. Simply pull it to remove it. Be careful, if you remove the filter after soaking it in hot water, it may be very hot to the touch. The cup screws onto the flask, making it easy to carry, and is made of double-walled stainless steel with no air gap.
Don't throw away, repair
Our products will accompany you on your mountain hikes. As you progress, they will age, some parts may wear out, break or get lost. To help you repair your flasks, our lids are available separately.
Materials and regulations
Our products and materials comply with current food contact standards. They do not contain Bisphenol A (BPA) in accordance with current French regulations. We have chosen to use 18/8 (304) stainless steel for the body of the flask, known for its food safety, and for the top part, a heat and impact resistant polypropylene.
Care advice
- Wash and rinse the entire product 3 times with clean water before first use. For optimal washing and drying:
1. Separate all parts; 2. Wash them by hand with soapy water (with a thin brush to get into corners and crevices). The flask can be washed in the dishwasher, but do not put the lid inside; 3. Rinse them with clean water; 4. Let them dry separately, the lid must remain open during drying.

How is thermal insulation tested?
We tested this flask in the laboratory 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 (drinking temperature considered warm enough to drink) is over 23 hours.
The secret of this insulated flask?
The double wall of stainless steel of this isothermal bottle with vacuum effect prevents heat conduction and convection. A thin layer of copper reduces thermal exchanges by radiation. Some tips to improve thermal insulation: Fill the bottle with hot water for 5 minutes, replace the water with hot liquids and then close it. The more filled the bottle, the better it retains heat. Note: the flask is very insulating, so liquids will remain hot for a long time.
Very insulating thanks to its double-walled stainless steel construction, the lid opens with 1 hand. Includes a removable tea filter, a double-walled cup and a carrying handle / 0.4L
