The Jetflow hydration system replaces a soft-sided bladder with a water bottle. Simply choose a reusable Nalgene bottle, water bottles, bottled sports drinks, soda bottle, or other beverage bottles. Most bottles fit! Unlike other hydration systems, Jetflow is quick and easy to clean. Snap the system apart and run the components through the dishwasher. That’s it! No mold, no drying racks, no hard-to-reach crevices. Just simple, clean hydration. To use: screw the bottle onto the Jetflow Manifold (included), the bottle rests upside down in the pack. Adjustable bite valve and hose length.
