Great easy-to-use bottle

I have been looking for a bottle that can be opened with one hand, and this is it! The flip cap has a lock that is easy to slide to unlock, and the sprout is not too small nor big for drinking. I have dropped it a couple of times from the table and so far it hasn't broke!

Étanche J’aime qu’on peu barrer l’ouverture pour qu’il n’y ait pas de fuite

Bonjour Sophie,

Merci pour votre commentaire, nous sommes ravis que vous soyez pleinement satisfaite par cette bouteille !

Au plaisir de vous retrouver très bientôt dans nos rayons !

Удобная, прочная, не протекает

Отличная фляга, конструкция крышки с замком и уплотнителем обеспечивает герметичность, пластик прочный, без посторонних запахов. Учитывая, что стоимость минимум в пять раз меньше, чем у брендовых спортивных фляг, у которых и с эргономикой проблемы, и с протеканием - вопрос о целесообразности покупки даже и не поставишь.

Бутылка для воды.

Удобно пить на ходу. Замок от случайного открывания.

Güzel ürün

Su içimi rahat. Ürün damlatma yapmiyor. Aç düğmesi aşağı indirirerek kilitleniyor. Ürünü yeni kullanmaya başladık. Uzun kullanımda nasıl olur bilmiyorum.

Additional Product Information



  • 100% Tritan

  • 1% Stainless steel
  • 8% Silicone
  • 10% Polyamide 6. 6
  • 81% Polypropylene

Directions for use

Tritan, like aluminum, is not an isothermal material. Use a specially designed insulating bag if you want to keep liquids cool in your water bottle. This water bottle can be used for hot drinks, but they will cool quickly. The product can be used with carbonated drinks. Do not put in the microwave or freezer.


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. It also has a filter, so you can infuse fruits, for example. The water bottle is transparent and graduated 200 ml by 200 ml to be able to see the remaining liquid.

Care tips

Clean your flask after each use with conventional dish soap and water. The product may also be placed in the dishwasher if necessary. Warning: When washing in the dishwasher, the stopper seal may come off. If this happens, remember to replace it, as it helps keep your water bottle watertight. Let the bottle and lid dry separately and fully. Soak overnight in a mix of baking soda and water for deep cleaning.

1st use

Rinse the entire product 3 times with clear water before using for the 1st time.

Materials and regulations

Our products and materials meet the food-contact standards in effect. They do not contain Bisphenol A (BPA) in accordance with the French regulations in force. Plastics are divided into 6 categories depending on their properties. If a plastic does not fit into one of these 6 classes, it switches to class 7 (where we find all kinds of food-grade and non-food-grade plastics). Tritan, suitable for food contact, fits into this category 7.

Weight and dimensions

Volume: 0.5 liter Size: Ø 2.8" x 8.5" Weight: 3.7 oz (Body 2.1 oz and top 1.6 oz) Available in: 0.5 L / 0.8 L / 1.2 L

Our environmental approach

We are aware that we need to act to preserve our natural playground; therefore, Quechua is committed to reducing the environmental impact of its products. This flask is produced nearest to regional markets (Portugal / China / India) with maximum reduction in packaging and transport packaging. The product is also guaranteed for 5 years in normal use conditions.

Don't throw away, repair

Our products will join you on your hikes. As you gradually progress, they will age, and 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.

Product design: our expertise

Our Quechua global design center 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 hiking products and providing you with all our expertise.



Product testing

To meet your requirements, Quechua products are tested in the mountains in conditions you will encounter during your hikes. Our teams, as well as a tester panel (made up of partners, ambassadors, and customers), test products throughout their development until they go to market.
