Not worth the price. I plan to return it as I don’t think the material is great. The label or description does not mention if it is BPA free or not.

Good quality

Use this bottle everyday without problems for a few weeks now. The seal is good, very comfortable to drink from. Dropped the bottle a few times without issues so far.

The opening of the bottle is so hard .

The design of the bottle was nice accept for the opening. So hard to open . You have to screw the cap on the bottle use ur 2 hand open up . I thought only mine is acception went back to the shop to test it is the same hard to open due to the rubber size of the cap

Dear Tiffany,

Thank you so much for the feedback. We really created the bottle cap to be super right to prevent leaking of the bottle. However, it is true that it can cause discomfort in the opening and closing, and we really want to address it.

I have sent this feedback directly to the product leaders and designers in France. We hope to improve the product so it's easy to use yet still remain watertight.

If you are unhappy with the product that it is unable to create the experience you expected, please feel free to drop by our stores to request for a refund or exchange.

Once again, thank you again for the feedback.

Practice on!

Hi Lynette!

Thank you for your review of the Quick Open Water Bottle!

I am delighted to find you're happy with this product! Yes indeed, it was made with a quick opening with only one hand. The top can be locked with the handle & it comes with a built-in filter! And, it does come in the colour Purple too!

Thank you again for taking the time to write your wonderful review! We look forward to seeing more of your reviews too! :)

Practice on and have a nice day!

Sport on safely!

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: 0.8 liter Size: Ø 3.1" x 10" Weight: 4.6 oz (Body 3 oz and top 1.6 oz) Available in: 0.5 L / 0.8 L / 1.2 L

Our environmental approach

Because we are aware that we must act to preserve our playground, Quechua is committed to limiting 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 our hiking products and providing you with all our expertise.



Product testing

To meet your requirements, Quechua products are tested in the mountains in conditions that you will come across 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.

Storage instructions

Wash and dry before storing. Store without closing. Store in a clean, dry place.

Superior quality. Unbeatable prices.

For 40 years, Decathlon has delivered the best value in the retail sports industry by offering high-quality, sustainable and cost-effective products.
