The fuller the flask, the better it is at keeping the contents hot or cold. Be careful when using hot liquids, the flask is extremely well insulated, liquids will remain hot for a long time! We use a double stainless wall with a vacuum between to block thermal exchanges by conduction or convection. To block exchanges by thermal radiation, a fine layer of copper covers the outside of the inner wall.

The top is easy to open with one hand by pressing on the white button marked "PRESS". 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.

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.

Rinse the entire product 3 times with clear water before using for the first time.

We have chosen an extremely resistant material for this flask (18/8 stainless steel), easy to recycle with recognised durability and food safety. We don't use any inner or outer coatings. The product is also guaranteed 5 in normal use conditions.

We also selected: - Solvent-free laser engraved branding. - Solvent-free paint (powder coating) to give texture to reduce condensation and improve grip. - Maximum reduction in packaging and transport packaging. - Factory manufacture using 100% renewable energy.

Our products will join you on your mountain walks. As you gradually progress, they will age, certain parts can get worn, broken or lost. To help repair your flasks, our tops are available separately. Our environmental approach at Quechua also supports making these parts available to you.

Our Quechua global design centre is based in Passy, at the foot of Mont-Blanc in Haute Savoie. This location makes it a real meeting place for our teams (designers, product managers, engineers, etc) and outdoor sports enthusiasts. A great asset for designing your mountain walking products and providing you with all our expertise.
