A water bladder designed for replenishing your water supply during trail runs.
With its 1L capacity, your water bladder will give you 2 hours of running time on average. Indeed it is often the minimum volume required during trail running competitions.And thanks to its wide open, you can quickly fill it at the drink stations. When closing it, you should feel the slide-top clip into place to ensure a perfect seal. Finally, your water bladder is compatible with the 5L, 10L and 15L trail running bags.
A tube and an adjustable bite valve for superior comfort.
You can easily cut the tube of the water bladder to your preferred length!To do this, remove the bite valve, put the tube in some hot water to soften it, cut it to the required length and replace the bite valve.The bite valve has an on/off closure system to prevent leaks during transportation. When running, it does not leak, even when it is in the open position. In order to get a good flow rate when you drink, pinch the bite valve with your mouth and suck!
Composition, dimensions and maintenance of your water bladder:
The components of your water bladder are guaranteed to be free of BPA (Bisphenol A) in accordance with current French regulations.It is 31 x 16cm in size with a 100cm tube.To prolong the lifetime of your water bladder, do not fold it, do not fill it with hot liquids and do not carry it upside down or by the tube ;)
How to empty the air from your water bladder
To avoid hearing the noise of the water splashing about in the pouch while you are running, make sure you empty out all the air before starting!Just hold your water bladder upside down after filling it, guide the air bubbles towards the tube opening and suck them out. That's all there is to it. Now you can enjoy the silence while you run!
Some tips for cleaning your water bladder:
To avoid any taste of plastic when you drink, rinse your water bladder 3 times before using it for the first time.Whenever you clean your water bladder, remember to dry it thoroughly by leaving it open.If the taste of plastic persists, put your dry water bladder in the freezer overnight.
How do we test a water bladder?
To guarantee the quality of the 1L water bladder, our design team asked 12 runners to use it during a running session on a treadmill.Because it is much more easygoing than trail running, running on a treadmill gives you the opportunity to concentrate on the flow rate of the bite valve, the movements of the water bladder and the user comfort. With the help of the feedback provided by our testers, we designed a product for trail running.
Product Reviews


Compared to other water bladders on the market that are in the same price bracket, the Decathlon one is very strong and well made. I have had multiple reservoirs split or leak on me and these ones seem ok so far.
It does what it should
Works well and lives a short life. Then takes its place on the enormous pile of landfill that us humans generate, often in the name of profit. Instead of making this hard-wearing, Decathlon choose to make it disposable. Well done! For those who want a product to work well and to last, I'd suggest you look elsewhere.
