Offering you flexible containers for your trail runs is the aim of our design team.
Compared with a rigid water bottle, your flask is lighter, less noisy when you run and does not hinder your movements as much.
When running, the water bottle won't create any pressure points on your body.

To prevent any taste of plastic, rinse your flask in clean water 3 times before using it. Then, dry it upside down without the mouthpiece.
You can remove the mouthpiece to clean it. This is particularly important if you are using sugary drinks!
Finally, so that it doesn't make noise while you are running, remember to remove any air by sucking out the air bubbles.This water bottle emerged out of an innovative process involving an odourless and neutral-tasting plastic material.

We have listened to your advice and have improved the opening system of the water bottle. That's why the top is wider to make it easier to clean the water bottle.
The extra wide opening is also designed to make it easier to add isotonic drinks in powder or tablet form.
We have also improved the visualisation and ergonomic handling of the opening and closing of the bottle. The top of the water bottle can be switched to the open or closed position by simply rotating the ridge.

With its 500 mL capacity, your flexible flask is useful for about one hour of running time, on average.
And in order to simplify your preparation and equipment, your 500 mL flask is compatible with all our trail running bags and belts!

The mouthpiece of the flask has an ON/OFF position. In the OFF position, you can avoid any nasty surprises during transportation. In the ON position, your flask will not leak while you are running: Pinch the mouthpiece and suck to drink.
Finally, the flask is designed so that you can drink without removing it from the front pocket of your bag.Please note that it's important to empty the air from the water bottle before you start running to avoid any nasty surprises...

In order to guarantee the high standard of the 500 mL water bottle, our design team asked 12 runners to use it and to comment on the flow of the bite valve, the ON/OFF opening/closing system and, finally, how easy it was to put the water bottle in the pocket of their bags. Using the feedback provided by our testers, we designed a product for trail running.
