Connect your GravityWorks water filter (and most other water filters) directly to a Big Zip EVO Reservoir without ever having to take it out of your pack. Just plug the hose into the base of the filter, insert the quick-disconnect fitting into the upper port on your reservoir, let gravity do the rest and you'll be on your way with clean, taste-free water.
