A large water bladder, sturdy and made in France.

With its 2-litre capacity, your water bladder will keep you hydrated for about 3 hours.With a wide opening for easy filling.
When closing it, make sure the slider clips firmly into place to ensure it won't leak.Tested in the laboratory and made in France, its puncture resistance has been improved by 74%.


Before leaving, squeeze the air out after filling so as to increase the flow rate of your drink.
Just turn the water bladder upside down, direct the air bubbles towards the tube opening and suck them out.
The mouthpiece is lockable (rotates 180°) to prevent leaks when not in use. It won't drip, even when in the open position. To drink, gently bite the mouthpiece and suck in!


2 sealable side pockets (telephone, cereal bars & tissues) & 1 pocket (multitool) underneath the bag for direct access.
With the 6 inside pockets, everything else easily finds its place (documents, keys, tyre lever, repair essentials, pump and water chamber).

The net on the outside can be used for gloves or a waterproof jacket. There are also clips on the outside to attach your helmet, glasses and a rear LED clip-on light.


To improve the resistance of your bag, we recommend waterproofing it. Even though the fabric is already water-repellent, extra waterproofing will stop mud getting caked onto it.

After each ride, remember to wash and dry your water bladder.

If you don't want to get a plasticky taste, put your dry water bladder in the freezer. This will stop any flavour transfer.
