500ml extruded soft flask for trail running

Our team of trail running enthusiasts designed this flexible 500ml flask to allow you to comfortably carry your drinks on all your trails.

A flexible flask for more comfortable trails.

Our design team strives to offer you flexible containers for your trail runs. Compared to a rigid bottle, your flask is lighter, less noisy when you run, and less restrictive. The flask won't cause any hard spots on your body while running.

How to maintain your flask?

To avoid the plastic taste, we recommend rinsing your flask with clean water 3 times before use. Then, dry it upside down, without the nipple. You can remove the nipple to clean it. Especially if you use sugary drinks! Finally, to avoid noise during the race, remember to create a vacuum by sucking out the air bubbles. This flask is the result of an innovative process with a plastic material that is neutral in taste and odor.

New, more ergonomic flange cap

We listened to your feedback and improved the flask's opening system. The cap is now wider to make cleaning your flask easier. It's also wider to make it easier to insert isotonic drinks, whether powdered or in tablet form. We've also improved the visualization and ergonomic grip of the opening and closing system. Simply turn the knob to open or close the flask's cap.

What autonomy and what compatibility for your flask?

With its 500 ml capacity, your soft flask will last you an average of one hour of running. And to simplify your preparation and equipment, your 500 ml flask is compatible with all our trail running bags and belts!

Tips for good hydration

The flask's nipple has an ON/OFF position. In the OFF position, you avoid unpleasant surprises during transport. In the ON position, your flask won't leak during the race: you have to pinch the nipple and suck to drink. Finally, the design of your flask allows you to drink without removing it from the front pocket of your bag. Note that it's important to empty the air from your flask before the race to avoid unpleasant surprises...

How is the 500ml flask tested?

To ensure the quality of the 500 ml flask, our design team asked 12 runners to use it and focused on the flow rate of the nipple, the ON/OFF opening and closing system, and finally the ease of inserting the flask into your bag pocket. The feedback from our testers allowed us to design a product perfectly suited to trail running.
