DESCRIPTION

Collapsible reservoir with drinking-tube assembly and 142 fl. oz. capacity turns any pack into a "hydration system" at a fraction of the cost. Big-Zip feature opens one end of reservoir for easy filling, cleaning or addition of ice cubes; zip-lock provides a watertight seal. Durable welded laminate construction lined with polyethylene film provides a lightweight, puncture-resistant reservoir that is guaranteed for life. Drinking-tube assembly includes a 42" long, high-flow hose connected to the reservoir cap and a no-hands bite valve complete with a lapel clip. Bag can be boiled, frozen, inflated, collapsed or just filled with your favorite refreshment; flat bottom allows bag to stand when filled.
