GeoPress® One-Way Drink Mix Valve
Give your GeoPress® a boost! In April of 2023, we redesigned our Cartridges to accommodate a One-Way Valve. It's a significant upgrade that includes a new "core" plus "flow channels" making it possible to add electrolytes, drink mixes and other flavored liquids into GeoPress.
Note: the GeoPress® One-Way Valve now ships pre-installed in every GeoPress.
