purified water with your Grayl.
Add electrolytes or a sport drink mix
to your filtered water (only if
One-Way Silicone Valve
is installed).

potable (i.e. safe to consume)
beverage vis a vis the Drink-Thru Cap.
ADD YOUR DRINK MIX
A Grayl® One-Way Silicone Valve
consists of four “duck bill valves” that
both prevent water (or other beverages)
in your bottle from backflowing through
the Cartridge and also allow clean
filtered water to pass through the
Cartridge into the Inner Press.
