Peut mieux faire !

Je passe du Rockrider 1L de la collection précédente à celui-ci. Quelques détails me gênent sur ce produit, à commencer par le tuyau de la poche à eau qui sort sous la bretelle, au lieu de dessus. Le diamètre du compartiment pompe à vélo bien trop petit, la pompe ne rentre pas. Les bretelles sont très fines, surement pour améliorer la ventilation, mais à l'usage, elles sont douloureuses. La sangle ventrale trop fine. Sinon j'aime toutes les petites poches pour ranger outils et nourriture. Et j'aime le prix et c'est pour cela que je fais avec les défauts listés.

La poche à eau…

La poche à eau reste parfois difficile à utiliser. La pipette fonctionne pas tjs très bien et il manque des accroches pour faciliter sont maintien où l'on a envie de lavoir pour une meilleure utilisation.

In a nutshell

Type of bag: hydration backpack Bag volume: 7 L Volume of water: 2 L Water bladder with fastening strip, hose, and bite valve included 6 inside pockets or nets 3 sealable outside pockets for easy access without removing the bag 1 outside net for gloves, a compact or windproof jacket 1 outside loop for glasses 1 outside helmet clip 1 insert for clip-on LED rear light 1 chest strap 1 waist strap Water-repellent

A large water bladder

With its 2-liter 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.

Getting good flow

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 toward 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!

Carry all your things

2 sealable side pockets (telephone, cereal bars, and tissues) and 1 pocket (multitool) underneath the bag for direct access. With the 6 inside pockets, everything else easily finds its place (documents, keys, tire 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.

Care tips

To improve the durability of your bag, we recommend waterproofing it. Even though the fabric is already water-repellent, extra waterproofing will stop mud from getting caked onto it. After each ride, remember to wash and dry your water bladder using the cleaning kit (product ref. 5935596). If you don't want to get a plasticky taste, put your dry water bladder in the freezer. This will stop any flavor transfer.

Eco-design: dope-dyed

Dying fabric requires soaking it in large amounts of water. To conserve and avoid this abundant use of water, we use a dope-dyed technique. This is a process by which coloring is added at the time the fabric thread is created. Dope dyeing is used on the black and plum-colored bags.

Eco-design: two-tone

Fabric dyeing requires lots of water, with large amounts of waste water also released from the dye vats. To reduce the impact of water consumption and waste water, we use only 1 dyed yarn out of 2. Two-tone dyeing is used on the plum-colored bag.

Extend the product's lifespan

Remember to take a look at our water bladder support page to make your water bladder last longer.
