Great idea

Like the concept, does not leak but water tainted by strong taste of chlorine even after several uses.. Could be much better if that was sorted out.

Easy to clean and user friendly

Better than other more expensive flasks and as it comes apart its very easy to clean properly. The only minor criticism is you have to put your fingers were you drink to open close the valve but it doesn't tend to leak so not too much of a problem.

Great handy bottle

Love this bottle, easy to drink from on the go and fits perfectly into the pouch I bought alongside it. Handy that it folds into very small and light once empty.

Soft Running Flasks

We must have eight or nine of these they are the best value for money, now with replacement tops which also extends their life. I always fill the night before and store in refrigerator over night, it makes them easier to load into trail vests in the morning.

Weird to get used to

Weird to get used to but great once you have. The main benefit being they pack down so well once all the liquid is gone. Obviously!

Great addition to my ultra training kit. I had had enough of the water bladders but still needed ample drink supplies. The way these fold down when finished is ingenious.

Flexible Flask

I used my Flexible flasks on Saturday for my first Ultra Marathon and found them great and easy to refill at water stations and easy to put them back into my trail running backpack.

A flexible flask making your trail runs more comfortable.

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.What's more, it occupies less space: You can compress it gradually as you drink the contents, thereby reducing its volume!

How to maintain your flask?

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. If the plastic taste persists, place your dry flask in the freezer.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.

What is the flask's running time and what is it compatible with?

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!

A user-friendly design when trail running.

Your 500 mL flask has a thumb hole. It can therefore be carried effortlessly even when you have pushed yourself to the limit during your trail run.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.

How was the 500 ml flask tested?

To guarantee the quality of the 500 mL water bladder, our design team asked 12 runners to use it during a running session on a treadmill.Much more relaxed than a trail run, running on a treadmill gives you the opportunity to concentrate on the flow rate of the mouthpiece, the taste-free water, the lack of any discomfort when using the mouthpiece, the movements of the flask and the user comfort.With the help of the feedback provided by our testers, we designed a product for trail running.
