How to use

Open the reservoir via the wide-mouth opening and fill with potable water or an appropriately diluted sports drink up to the recommended level. Close the reservoir using the slide-clip sealing system, ensuring the seal is aligned and fully engaged. Place the bladder into a compatible vest or backpack, route the drinking tube through the pack’s hose port and attach the bite valve for hands-free access. After use, rinse the reservoir with warm water, reverse it to allow full access for cleaning, and let it dry completely before storing.

Recommendations

To maintain hygiene and prolong the life of the reservoir, rinse after each use, periodically perform a deeper clean with a mild detergent or specialised cleaning tablets, and allow the bladder to air dry fully reversed. Avoid storing liquids for extended periods and do not expose the reservoir to direct sunlight for prolonged times when filled.
